That formula works fine. It does exactly what you asked it to do.
For any row where the content of column B equals the content of column C in
the same row, the sign of the content of row D is added to the total.
If that wasn't what you wanted to do, you needed a different formula.

You asked a different question originally, and Luke and Jacob answered that
question, but it isn't clear what you now want to do.

Hi Luke,

You guys did but this one is a little different. I want to be able to
write
like this:
=SUMPRODUCT(($C$2:$C$20=$B$2:$B$20)*(SIGN(D$2:D$20 )))

this one does not work because I change "B2" to "B2:B20".

Didn't Jacob and I already answer a similar question?

In E2:
=SUMPRODUCT((C$2:C$20=B2)*(SIGN(D$2:D$20)))

Copy down as desired.

Hi All,

I have 2 tables one is cust table and the other one is amount table.

A B C D
Customer Table Amount Table
Parent ID Cust # Cust # Amount
2001 AA AA 5
2001 BB AA 5
2001 CC AA 5
2001 DD AA 5
2001 EE AA -5
2001 FF AA -5
2001 GG BB 3
BB 3
BB -3

Summary

AA - I want to be able to count if "AA" in Cust table (Column B) then
count
positive amount minus negative amount in amount table (Column D). In
this
case the answer is "2"

BB - The same thing with "BB". The answer is "1"
Thank you
John
