Kevin,

Your last reply did the job. I used a combination of the COUNTIF statement
and the COUNT statement you gave me and everything worked perfectly. The
COUNT statement really was the key. I had the logic, but didn't include the
COUNT function in my statement.

I skipped a row because the name of each month spans two merged cells. And
I named my data ranges (because they were every 2nd cell) which really
simplified things.

Now my spreadsheet is blank when it's empty, calculates some stuff as it is
entered and doesn't calculate other things until all cells in the range are
complete. It's perfect.

I guess I don't really understand the power of some of the functions so I'm
thinking I need a book or tutorial site to get a little further up to speed.

Thanks again!

Matt

I don't know if this will solve all of your problems, but you probably want
to change the formula to the below and see if that gets you going in the
right direction:

=IF(COUNTIF(B5:Y5,"=0")=COLUMNS(B5:Y5),AVERAGE(B5 :Y5),"")

You are now dealing with a count of columns rather than rows (as you are
going across, not down.)

I don't know if this will completely solve your problems as you seem to want
to skip every other column.

The average formula in AA5 is this:

=IF(COUNTIF(B5:Y5,"=0")=ROWS(B5:Y5),AVERAGE(B5:Y5 ),"")

When all cells from B5:Y5 are blank and Average is not calculated.
When data is entered into B5 (January) AA5 calculates
When data is entered into D5 (February) AA5 goes blank

I've used several much simpler statements but get stuck with a #DIV/0! error
in this same field.

You know what I'm going for. I wish I could upload the spreadsheet. There
are a total of 8 fields in each month that need to be populated. All the
remaining fields should perform calculations on the data that is entered into
these fields. If there is nothing to calculate then everything should be
blank. Not have 0's, or $ -, or DIV/0 errors and so on.

On a much smaller scale I was able to use simple IF statements to prevent a
calculation of the adjacent field wasn't populated. These broader scale
calculations are driving me nuts.

Looks to me like your reply to my 2nd question worked. I'm not sure how or
why but it did what I needed. Perhaps I can COUNT or COUNTA for the rest of
my calculations.

Thanks for helping me. I'll keep my eyes peeled for your next post.

I don't know why your average formula would go blank. What is the formula in
AA6?

For your 2nd question, this formula should work:

=IF(COUNT(A8:A13)0,SUM(A8:A13),"")

Kevin,

I looked at everything again and I'm afraid I'm not where I need to be.
Bear with me. I'm not sure if I worded my question well enough.

I have a table in which each column represents a month. The first line of
each column is a total of the 7 lines below it. The last column is an
average of each monthly total.

1st. I'd like to keep a running average of the totals in each month. If
there is no value entered in the 'Total' cell for a month I don't want "0" to
show up. Using the statement you gave me before all of my 0's went away when
the 'Total' cells were blank. When I entered a total into January (b6) the
average calcualted in AA6. But when I entered a total into February (d6) the
average in AA6 disappeared. What's the fix?

2nd. I'd like to keep a running total of jobs for the month. In January
these would be cells a7:a13. If I just use SUM there is a 0 in a14 until
data is entered into one of the cells a7:a13. I'd like a14 to stay blank and
calculate a total as each cell is populated:

a7 = 5
a14= 5

a7=5
a8=5
a14=10 ---and so on.

What am I missing?

My sumrange was a1:a10 so rows(sumrange) returns 10. The countif will count
the number of occurences where the cells in sumrange = 0. If all of the
cells meet the criteria, this will equal 10. Therefore the true portion of
the IF statement will be returned which is SUM(Sumrange). Otherwise ""
(nothing) will be returned. This per your latest request to have "" shown
rather than ).

Kevin, Andy, thanks for the quick responses. Both of your formulas worked
(as far as I can tell). I'm interested in understanding how they work if you
could offer a quick explanation.

Moreso, I need a little more help. Both the formulas returned a 0 when
summing a range of blank cells. Here's the issue, this spreadsheet is pre -
formatted for a year's worth of data. I'd like for the cells in an unused
month to remain blank until the data is entered (and subsequently
calculated).

There is currently no user added data in cells b6:b12. But cell b13 that
calculates the total of b6:b12 shows 0. I'd like it to be blank until data
is entered into b6:b12. How can I concisely do that?

I thought about using IF and OR functions combined so that each cell is
checked for a value greater than "" before it will calculate the total of the
cells but it's very long and I think inefficient.

Got anything else?

Thanks

Hi

Try something like this:
=SUMPRODUCT((D7:G70)*(D7:G7))

I'm looking to total a range of cells ONLY if they have a value of 0 or
more
entered in them. In plain english:

Sumif A1 is =0
Sumif A2 is =0
Sumif A3 is =0

and so on. Where every cell in the range must have a value of 0 or more
entered before the function will return a result. How do I do this?

Thanks,
