If you don't want to stretch the clairvoyant powers of the group, it might
be handy if you tell us what error message you're getting. Where in the
formula does the cursor sit when Excel reports the error?

What do your windows regional settings use for separators? Are you sure
that lists are separated by commas, or might they be semi-colons in your
system?

Assuming there is a date associated with each sale:

=SUMPRODUCT(--(MONTH(A2:A100)=6),B2:B100)

Column A contains Dates
Column B contains Sales

Above give sales for June (ignoring year)

=SUMPRODUCT(--(MONTH(A2:A100)=6),--(YEAR(A2:A100)=2007),B2:B100)

Above give sales for June 2007
