Hi!

Based on what your formula is actually doing, try this:

=COUNTIF('sales thru 9-16-05'!$1:$1,Summary!$B2)*COUNTIF(OFFSET('sales thru
9-16-05'!B$2:B$1433,,(ROW(1:1)-1)*1),TRUE)

=SUMPRODUCT(('Sales thru 9-16-05'!$1:$1=Summary!$B2)*('Sales thru
9-16-05'!B$2:B$1433=TRUE))

While filling down, I want the reference in the second criteria to
change from B$2:B$1433 to C$2:C$1433, then in the next cell down
D$2:D$1433, etc.

Does that help?
