HI, I am trying to use conditional formatting to make sure that bar codes created on a label match the correct numbers. Right now I have Column A with all of the numbers the scanned in codes should match, I have made it so the corresponding cells in column B are to turn red when the codes do not match, however for some reason only some of them are actually working when scanned in. Is there some specific format I can lock into each cell to make sure the check works?

Thank you!
