Basically I'm creating a spreadsheet that has formulas in place so that the user simply has to enter data and a score will be given. I have a row of cells that show '-66' because it will take 66 away from 0 unless there is any data there. So, basically I want to say "if this cell is minus 66, show either nothing or something like --" Also how can I hide a result of 0?
EDIT - IGNORE, I think I've done it.
