I think I'm in need of some type of index & match formula. I have column
headings that are dates and below them are a series of numbers. I would like
a formula that adds the numbers below the column headings based on today's
date. For example, in column AN I have a column heading of 1/1/07 and below
the column heading I have numerical data in rows 3 -15. In column AT I have
the column heading 2/1/07 and in Column AZ, I have the column heading 3/1/07.
This continues in the same pattern for each month of the year and below each
column heading is data in rows 3 - 15. I would like to add the cumulative
total of each row for each column depending on the date. Since today is 3/3,
for example I would like to add the total of Cells AT3 and AN3 in one cell
and then have a similar formula for each of the rows 4-15. On 4/1 this
formula would add to the previous totals the data in Column AZ rows 3 - 15.
Would appreciate any help you could provide. Thank you in advance for your
assistance.

If I understand what you're asking for correctly, I think we can do this
another way (not sure if INDEX/MATCH would work anyhow).

If I understand you, you want a formula on row 3 (or somewhere) that will
total the values in columns AN, AT, AZ, BF, BL, BR, BX, CD, CJ, CP, CU and DA
based on the month and day of the month. For row 3 in those columns, the day
of the month must be the 3rd or after, and the month must be less than the
current month (using TODAY()). So on the 5th of April, the formulas should
return results for the 3rd, 4th and 5th of Jan, Feb and March.

We can use a relatively simple formula repeated with minor modifications to
get the answer.

These formulas are assumed to go in the same row (3 through 15) that you are
interested in. Here is the basic format of the formula for the values in row
3 (3rd of the month)
=IF(AND(MONTH(AN$1)<MONTH(TODAY()),(DAY(TODAY())= ROW())),AN3,0)
to modify that to get the value for Feb, column AT all we do is change the
two instances of AN in it:
=IF(AND(MONTH(AT$1)<MONTH(TODAY()),(DAY(TODAY())= ROW())),AT3,0)
we can repeat this logic all the way through November, but December is a
special case since there is no month #13.
for December (column DA) the formula would look like this:
=IF(AND(MONTH(DA$1)=MONTH(TODAY()),(DAY(TODAY())= ROW())),DA3,0)

What we do is simply add the results of these tests together in a single
formula (looks long and ugly, but examine it and you'll see it is just the
basic formula repeated 11 times plus the December formula and adding the
results of each together:

=IF(AND(MONTH(AN$1)<MONTH(TODAY()),(DAY(TODAY())= ROW())),AN3,0)+IF(AND(MONTH(AT$1)<MONTH(TODAY()),( DAY(TODAY())=ROW())),AT3,0)+IF(AND(MONTH(AZ$1)<MO NTH(TODAY()),(DAY(TODAY())=ROW())),AZ3,0)+IF(AND( MONTH(BF$1)<MONTH(TODAY()),(DAY(TODAY())=ROW())), BF3,0)+IF(AND(MONTH(BL$1)<MONTH(TODAY()),(DAY(TODA Y())=ROW())),BL3,0)+IF(AND(MONTH(BR$1)<MONTH(TODA Y()),(DAY(TODAY())=ROW())),BR3,0)+IF(AND(MONTH(BX $1)<MONTH(TODAY()),(DAY(TODAY())=ROW())),BX3,0)+I F(AND(MONTH(CD$1)<MONTH(TODAY()),(DAY(TODAY())=RO W())),CD3,0)+IF(AND(MONTH(CJ$1)<MONTH(TODAY()),(DA Y(TODAY())=ROW())),CJ3,0)+IF(AND(MONTH(CP$1)<MONT H(TODAY()),(DAY(TODAY())=ROW())),CP3,0)+IF(AND(MO NTH(CU$1)<MONTH(TODAY()),(DAY(TODAY())=ROW())),CU 3,0)+IF(AND(MONTH(DA$1)=MONTH(TODAY()),(DAY(TODAY( ))=ROW())),DA3,0)

you can actually put that into a cell in row 3 and then fill it down to row
15 (and beyond) and it will work. Since you only go to row 15, we don't have
to worry about months with <31 or <30 days, all months have at least 12 days.

As written, there may be an effect you don't want - the values in the
formulas will always be zero after the current day of the month for all
columns. I mean if it is Dec 4, then you'll only see entries in rows 3 and 4
because of the day checks in the formulas. If you need to see all 12 rows
for months Jan-Nov with values for Dec added to rows 3 and 4, then I've got
some additional work to do.

Or maybe what I've done will inspire someone to do some other creative
thinking and come up with a simpler formula that deals with the days and
offsets between columns better. I actually thought about doing this with
OFFSET() and some formula involving the month and day, but haven't delved
into that yet. My gut feeling on that at this point is that it is a 6 of
1/half-dozen of the other kind of deal, with a formula using OFFSET() looking
even uglier.

Damn, that's sweet - but take a look at it a little close, I'm coming up
short 2 months. I filled each of the columns from 3 to 15 with increasing
values starting at 1, so for 12 months with date after 3rd, I'd expect to get
a total of 12 for that row, but I'm only getting 12. I put your formula into
both columns AJ and AL with the same results: 10 instead of the expected 12.
To test on out into the future I changed the formula to point to a cell with
a manually entered date instead of using TODAY() just to test this kind of
thing.

For my test date I used 1/4/2008 and just cannot get it to come up with
anything but 10 for those.

But yours takes care of the whole situation much better than my ugly beastie
in general - specifically the values in rows corresponding to days after
current day of the month.

Let me clarify:
I filled up rows 3-15 in each of the columns with values 1 through 12, and
the total I'm getting when using a test date of 1/4/2008 is only 10, not the
expected 12.

I interpreted the post differently than you.

I read it to mean there is a single date for each month (the first of each
month) spaced evenly every 6th cell starting from column AN and the OP is
basically looking for a YTD sum.

First: Apology - the reason I was getting 10 vs 12 was that between October
and November I only had 4 empty columns, not 5, so that threw
November/December out of "view" of your excellent formula.

I also don't think that the way you interpreted it will affect things at all
since he is depending on TODAY() rather than some typed in date.

I think your solution is the one he's looking for.

You get a HELPFUL from me - I'd thought about using SUMPRODUCT() also, but
hadn't gotten past the offsets between columns and had not even thought about
MOD to get there. Definitely helpful in my learning curve.

The double unary "--" coerces those logical values to numeric values:

formula
into
both columns AJ and AL with the same results: 10 instead of the
expected
12.
To test on out into the future I changed the formula to point to a cell
with
a manually entered date instead of using TODAY() just to test this kind
of
thing.

For my test date I used 1/4/2008 and just cannot get it to come up with
anything but 10 for those.

But yours takes care of the whole situation much better than my ugly
beastie
in general - specifically the values in rows corresponding to days
after
current day of the month.

I think I'm in need of some type of index & match formula. I have
column
headings that are dates and below them are a series of numbers. I
would
like
a formula that adds the numbers below the column headings based on
today's
date. For example, in column AN I have a column heading of 1/1/07
and
below
the column heading I have numerical data in rows 3 -15. In column
AT I
have
the column heading 2/1/07 and in Column AZ, I have the column
heading
3/1/07.
This continues in the same pattern for each month of the year and
below
each
column heading is data in rows 3 - 15. I would like to add the
cumulative
total of each row for each column depending on the date. Since
today
is
3/3,
for example I would like to add the total of Cells AT3 and AN3 in
one
cell
and then have a similar formula for each of the rows 4-15. On 4/1
this
formula would add to the previous totals the data in Column AZ rows
3 -
15.
Would appreciate any help you could provide. Thank you in advance
for
your
assistance.

Why does the MOD function get set to "=4"?

We need to find a criteria that is common to the specific columns where your
data is located.

Column AN = column number 40
Column AT = column number 46
Column AZ = column number 52

This pattern of every 6th cell repeats to the end of your range.

What is common about those columns is that when you divide the column number
by 6 the remainder is 4:

=MOD(COLUMN(AN1),6) = 4
=MOD(COLUMN(AT1),6) = 4
=MOD(COLUMN(AZ1),6) = 4

The formula limits the calculation to only those columns where the mod of
the column number equals 4.

the MOD function get set to "=4"? Promise not to bother you w/ this
formula
again.

These expressions will return arrays of either TRUE or FALSE

(MOD(COLUMN(AN3:IV3),6)=4)
(AN$1:IV$1<=TODAY())

The double unary "--" coerces those logical values to numeric values:

--TRUE = 1
--FALSE = 0

before

I interpreted the post differently than you.

I read it to mean there is a single date for each month (the first of
each
month) spaced evenly every 6th cell starting from column AN and the OP
is
basically looking for a YTD sum.

Damn, that's sweet - but take a look at it a little close, I'm
coming
up
short 2 months. I filled each of the columns from 3 to 15 with

to

Actually, that should read:

We need to find a criteria that is common and unique to the specific columns
where your
data is located.

For example, if we tried using a divisor of 2 the remainder would be 0. But
this criteria includes columns that are not the specific columns of
interest. This criteria would include columns:

40,42,44,46,48,50,52

So, using a divisor of 6 sets the mod equal to 4 and this criteria is both
common and unique to only those columns of interest.
