Hi everyone. I am fairly new toi Excel but I have a problem.
I have cell A, B and C. The user ads data to A and B, and in C is a formula of the sum of A and B. The problem is that every end of the month the user delete's A and B and enter new values in both. The user don't want C to change but add the the sum of the new A and B plus the old value in C.
How can I do this. Please email solution to firstname.lastname@example.org
