I have the following example

A
1 aaa 1
2 aaa 2
3 bbb 3 X
4 ccc 4
5 ccc 5
6 3
7 3
8 9

Cell A1 contains "aaa"
Cell B1 contains "1"
Cell D3 contains "X"

Formula in B6 is =SUMIF(A1:A5,"A",B1:B5) and returns 3
Formula in B7 is =SUMIF(A1:A5,"B",B1:B5) and returns 3
Formula in B8 is =SUMIF(A1:A5,"C",B1:B5) and returns 9

I want to be able to add a function that will allow me to control the
formula by whether there is an X on the same row a cople of columns over.

So if I put an X on the same line a couple of columns over the formual will
do nothing.

Is there a way to do this?

Thank you.
