Thanks for your efforts,,, I know it's a bit confusing... the body sites had to be the same - and all i really wanted to compare - the exam codes are related but did not necessarily need to be the same - I guess I just didnt explain it well enough - that the exam codes could be the same or different - and have no impact on the True/False value - only the body site needed to be measured.

I appreciate the time you spent though


Very sincerely,

Steve
