Hi Seeker

Thanks for your reply.

A1:A65536 is converted to A:A (the entire column) and excel functions can
not handle an entire column (or row) as reference in versions prior to excel
2007.

Hi Per,
Thanks for your prompt reply and your answer works.
Just want to know further reason of while range is A1:A65535 or A2:A65536
(1
line short of full rows), it is no problem in extracting the sum but shows
#Num if I change the range to A1:A65536?

Hi

Maybe this is what you need:

=SUMPRODUCT(--(A1:A65535="xxx");--(E1:E65535="bbb");F1:F65535)

Thus end row can auto change to the last row?
like
=SUMPRODUCT(--(A1:A"counta(A1:A65536)"="xxx"),--(E1:E"counta(A1:A65536)"="bbb"),(F1:F"counta(A1:A6 5536)"))
