SUMPRODUCT
Okay -- sorry. I typed the formula in my original message incorrectly. Here
is the type of formula I've actually been using that is not working:
=SUMPRODUCT(Month(A1:Z1)=1,A2:Z2)
What am I doing wrong???

I have a spreadsheet that looks something like:
Row A 1/1/07 1/2/07 1/3/07 .... 12/31/07
Row B 4 2 5 .... 9
I would like to sum everthing in row B within a certain month. I have tried:
=SUMPRODUCT(Month(A1:A365)=1,B1:B365)
This is not working. Would someone tell me what I'm missing?
Thanks so much.
