Hello, I am sorry I am having to ask such a simple question for experts on this board, but I have tried google and I am clueless. I have one column. In that column are dates that personnel qualified. It expires after one year. I just want to put the dates in and see the color change from something like green (completed qualification recently) to red (expired or close to) If this is impossible, what would be the next closest solution? Thank you in advance for the help.
