It's hard for me to tell what's going on without seeing sample data. Perhaps
you could list a sample of 9-10 rows from columns D and F and tell us your
expected results?

Thanks Ken,
I've changed it to...

=sumproduct((F2:F100=DATEVALUE("1/1/2004")/(countif(D2:D100,D2:D100)+(D2:D100=""))

but I am getting a result that is a few short of what it should be. Any
ideas? I'm going crazy here!!

Thanks.

Hi Naomi,
When you reference dates in formulas like this, the syntax is:

F2:F100=DATEVALUE("5/5/2003")

Hi,
I have a unique count using a sumproduct formula like this...

=sumproduct((D2:D100<")/(countif(D2:D100,D2:D100)+(D2:D100="")

which seems to work ok. The problem is I then want to add another criteria
saying only count uniques where the date in column F = "01/01/05". Nothing
I've tried seems to work.

Thanks in advance!
