Paul,
The example you gave works well, but I have a question. Why do I need to
specify the rows in the formula?
I tried this, And I get a #NUM error.
=SUMPRODUCT(--('Grindex 2008'!AB:AB="Jan-2"),--('Grindex
2008'!Y:Y="Jan-D"))+SUMPRODUCT(--('Grindex 2008'!AB:AB="Jan-3"),--('Grindex
2008'!Y:Y="Jan-D"))
The only way I can try to get all rows is to use this:
=SUMPRODUCT(--('Grindex 2008'!AB1:AB65535="Jan-2"),--('Grindex
2008'!Y1:Y65535="Jan-D"))+SUMPRODUCT(--('Grindex
2008'!AB1:AB65535="Jan-3"),--('Grindex 2008'!Y1:Y65535="Jan-D"))
Any ideas?
Thanks,
Jay

You cannot use full column ranges when using SUMPRODUCT. You must specify a
range.

Ah, didn't realize that.
