It depends on the Excel version, 2003 and later can ignore hidden as in
formatrowhide,
earlier versions can ignore hidden by a filter
Also if you are going to use unary minuses it should look like this\


=SUMPRODUCT(--(A1:A2000=C1),--(B1:B2000=D1))

otherwise you might as well remove it and use


=SUMPRODUCT((A1:A2000=C1)*(B1:B2000=D1))



Anyway with 2003 and later and hidden rows as opposed to filtered rows us

=SUMPRODUCT(--(A1:A2000=C1),--(B1:B2000=D1),SUBTOTAL(103,OFFSET($A$1,ROW($A$1:$A $2000)-MIN(ROW($A$1:$A$1000)),,)))

Not sure if this can be done??

I have a worksheet where a number of the rows are hidden and need to
exclude these from calculations performed using SUMPRODUCT, ie;

=SUMPRODUCT(--(A1:A2000=C1)*(B1:B2000=D1))

but only looking at rows that are not hidden.

Is there a relatively simple way of doing this? If not I will just create
another column to show an 'X' when the row is not to be counted and then
make the calculation:

=SUMPRODUCT(--(A1:A2000=C1)*(B1:B2000=D1)*(E1:E2000<"X"))

Thanks.
