Stumped again.
I need a way to find a value in a column which has one or more corresponding values in an adjacent column. Then take all of the corresponding values found and count all occurrences of the found values in another column. But I only want to count the entries if an adjacent column is not blank.
Not the easiest thing to describe. Starting to wonder if I need to think in reverse. I hope the attached example makes more sense.
Any ideas are greatly appreciated.
