Hi
what is the formula you have used and what exact error do you get.
Note: you can't use a range A:A together with SUMPRODUCT.

For an explanation see:

Hi Frank
this gives me an error. I've changed the A1:100 ranges to my one. Any
ideas. Using 2002 version. Also what do the -- mean

I have a column with dates and another with totals. I want to for
every month
(01 - 12) to search all the rows in columnA and sum the totals only
relevent to the month from columnB. E.g for OCtober the total is
1500 ColumnA columnB
10/10/04 1000
10/10/04 500
10/09/04 250
