Your first post implied you're aggregating in 3D which is why you are using COUNTIF within SUMPRODUCT.
Assume you have 2 data sheets titled "Sheet1" and "Sheet2" - both sheets are identical in layout containing names in Column A (A1:A10), status in Column B (B1:B10)
Your intention on Sheet3 is to count how many people on Sheet1 & Sheet2 are both "Active" and called "David"
In Sheet3 A1 we type: Sheet1
In Sheet3 A2 we type: Sheet2
In Sheet3 A3 we type: David
In Sheet3 B3 we type: Active
In Sheet3 C3 we enter following formula:
Hopefully that makes sense.
If you're not aggregating in 3d (across multiple sheets simultaneously) then you do not need to use SUMPRODUCT.
