Hi Dave,

Let me apologize for posting this 3 times. Something strange is going on
with Google Groups and none of my groups are showing any postings beyond
October 3rd, including this one. I had to come into Microsoft's website to
find this, which I'm glad I did.

Anyway, thanks for your formula. It worked great, but I don't know if you
noticed that I added a second part to say if the date falls within a range.
For those interested, I got it working like this:

=SUMPRODUCT(--($B$5:$B$59DATE(2008,9,30)),--($B$5:$B$59<DATE(2008,12,31)),--($D$5:$D$59=C69),$F5:$F$59)

Thanks again for your continued support. You're great!

Michele

P.S. - Is there a simple explanation for those double dashes or somewhere I
can read about them?

Adjust the ranges to match--but you can't use whole columns (except in xl2007).

=sumproduct() likes to work with numbers. The -- stuff changes trues and falses
to 1's and 0's.

Bob Phillips explains =sumproduct() in much more detail he

Hi All,

This doesn't work:

=IF($B$5:$B$59<39721,SUMIF($D$5:$D$59,C65,$F$5:$F$ 59)) - entered as
Ctrl-Shft-Enter

I'm trying to get a total amount in column F if the date in column B
is less than 39721 (30-Sep-08), and column D matches C65.

Then I need the same thing, but with the date within a range, e.g. $B
$5:$B$5939721<39813 ...

I hope someone can help.

Thank you,

Michele
