I use this formula:

=SUMPRODUCT(--(Sheet1!$Y$4:$Y$903=Sheet2!G$10);--(Sheet1!$AB$4:$AB$903="Directed");--(Sheet1!$I$4:$I$903=Sheet2!E11);--(Sheet1!$AC$4:$AC$903=60);Sheet1!$N$4:$N$903)

The values in Col N are not numbers. The formula returns 0 (zero).

Is there a way to modify the formula to count the number of cells that
satisfy the 4 criteria ?

Thank you in advance.
