Sum.if date is in an interval...
Duh, for some reason I had a "#missing!" value in my column and that appeared
in row 6780... so, please ignore my previous post!

Yes, that's what I tried first, but I tried to count the letters A, B, C and
D. And this was not working, maybe letters are reserved?
Anyhow, thanks a lot for invaluable help! :

Instead of two criteria and one data, just use three criteria, such as
=SUMPRODUCT(--($A$1:$A$10<=F1),--($B$1:$B$10=F1),--($D$1:$D$10="Apples"))

This works like a charm.
Now I just want to calcluate the number of occurances of a string in
column
D (e.g., the number of times "Apples, Oranges") are listed in the column.
That is, same setting, but instead of summing numbers I need a similar
function, but that is counting a particular string.
Is that doable?
Kindly,
Mikael

I made up a List1 in A1:C10, and a list of dates for List2 in F1:F5
In G1 I used the formula
=SUMPRODUCT(--($A$1:$A$10<=F1),--($B$1:$B$10=F1),$C$1:$C$10)
I copied this down to G5
Not tested with much data but seems OK
You lists will be longer so use formula in the form
=SUMPRODUCT(--($A$1:$A$3000<=F1),.....
It CANNOT be used with full-columns =SUMPRODUCT(--(A:A<=F1)......

This may sound easy, and I thought it would be easy, but after som
thought
I
realize that what I'm trying to do probably requires a bit of
hard-thinking.
I have got a table that I exported from my database (Access) and it has
3
columns (call this list1)
1. Date1
2. Date2
3. A value
Now, I have created another column with dates (in chronological order),
ranging from 2005-01-01 to 2007-10-31 (call this list2) and I want -
for
each
of this dates - to have a SUM of all values THAT have the date in their
interval (interval between Date1 and Date2).
So, for my first date in list2: "2005-01-01" I want to have a total sum
of
all values in list1 where "2005-01-01" is between Date1 and Date2.
And so on for rest of the dates in list2 (2005-01-02 -- 2007-10-31).
(I really need this for a much promised and anticipated report
analyzing
our
sales, so all help is MUCH appreciated)
Cheers,
Mikael
