There's an example here that counts visible cells in a filtered column.
You could modify the SUMPRODUCT formula to reference your cells, and add
one more argument that refers to the cells to be totalled.

In the above example, the modified formula:


=SUMPRODUCT(SUBTOTAL(3,OFFSET(A2:A10,ROW(A2:A10)-MIN(ROW(A2:A10)),,1)),
--(A2:A10=A12),--(D2:D10))

would total the visible cells in column D.

I have a formula at the top of a columnn to calculate the SUMPRODUCT.
However, I need the SUMPRODUCT to recalculate the visible cells only
when I filter the column. I don't think that the SUBTOTAL function
will work. Any suggestions?
