Try this:

=Sumproduct((A1:A100="N")*(B1:B100="Y")*(C1:C100=" Z"))

You *cannot* use total column references (A:A), and all ranges *must* be of
equal size.

Hi,

I'm working with Microsoft Excel 2000 and I am trying to obtain how to
count
the number of rows that correspond to a variety of column criteria (e.g.
column A is equal to "N" and column B is equal to "Y" and column C is
equal
to "Z") but can't seem to work out an easy function to do this.

Can you please help ASAP?

Thanks,
Steve Boscoscuro
