Hi, I'm trying to find a solution to my problem, in fact I have worked on this before, but I don't remember how to solve it.
Basically I want to fill an array, looking up information on two columns..and when there is a match in both, I need a 1 to display, and a 0 otherwise.
There is an example attached, It's far more clear than any explanation.
I would really appreciate your help.
Thanks in advance.
