I have an additional question. I used calculation and it works. What I want is if I have variables A & B and I have a consistency check that asks the sum of A+B, I need this consistency check question to be asked if A & B has values...i.e if A=10 & B=10, but if
A=10 & B=-99(my code is don't know)...I want to skip the consistency check question to be skipped.
Please help me
