Excel/creat a dropdown if previous cell =
Hi Aiden its been a long time. I am in need of your expertise again. I have 2 columns (A and B). Cells in column A require customer to input 0,1,2,3,4. Cell B also needs 0,1,2,3,4. but if one cell has 0 then the other has to have 1,2,3,4 and the same goes for the other.
If cell A has 0 then cell B has to have 1,2,3,4 not allowing user to input 0.
Likewise, if cell A has 1,2,3,4 then Cell B can only have 0 not allowing user to input any number other than 0.
I tried to make a dropdown and was successful but this only asks user to input the numbers for either column and allows them to do it wrong. Users put 0 in both A and B and or 1thru4 in both A and B. First can this be done and 2nd how. In my head it seems easy but in excel not so.
Thanks for your input.
it's actually quite tricky (as you guessed) - I've only managed to do it using a "helper" column and an array formula. This version assumes that the A cell is A1
enter by pressing ctrl shift enter - the -1 should be replaced with whatever number you need to get the row count to start at zero, and A1 replaced with whatever cell has the value you want to exclude. This column is then the source of the data validation list. People who are determined to put rubbish answers can do it by overwriting the first value in column a with a duplicate, but I think that's unlikely to happen!
