Hi,
Can someone help me with the following (don't know if it is possible):
I have a simple table:
A B C
120 20 21
Now if someone changes B or C I want them to get a warning (data validation) if B+C NOT EQUAL to A. However there is a but, I want that someone to be able to change both B and C before they get the warning. Is this possible?
I tried a couple of things but couldn't get it to work.....
Thanks in advance ,
B
