What I'm trying to do is create a composite measure of each risk so that all 9 permutations can result in a unique number. This way I can prioritize the risks based on their overall "risk rating." My intent is to show the coun't of risks in a 3x3 grid. The problem is my math ability. How can I come up with a calculation that results in 9 unique values based on this? For example, since 1*2 is the same as 2*1, I cannot easily distinquish a low probability risk with medium impact from a medium probability risk with a low impact, which would result in a different placement on the grid.

Since nested IF statements can only handle 7 situations, and I have 9, I can't take that approach. I thought about a sumproduct approach from within each square on the grid, but that gets messy. I figure a single number will make it quite easy to count.

Ideas?

Thanks in advance. Wayne
