SUMPRODUCT
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. Ellen |

=sumproduct() likes numbers:
=SUMPRODUCT(--(Month(A1:A365)=1),B1:B365) But be careful. An empty cell will look like it has a month() of january. =SUMPRODUCT(--(Month(A1:A365)=1),--(a1:a365<""),B1:B365) might be better.

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???
