Excel changing 200 to 2.0

Hi, this worked, thank you so much! As for why it suddenly started happening in the middle of the sheet, I moved to a new laptop recently with a fresh install of excel on it, so this makes sense! I must have had it off on the old one, I had to change something in that area to do with zeroes once, so it was in the back of my mind, which is why I'd thought that there was still something I was missing. Thanks again!
