I don't know a lot about Excel and have created a simple spread sheet to track budget spending. In the "total" column I have entered the formula =O14-N14+(N14*0.3030769), this formula is in cell P14 and I would like it to remain blank until information is entered in to either O14 or N14, but curently cell P14 has a zero in it. Any suggestions on how I might alter the formula to have it remain blank until information is entered into cell O14 or N14? Thanks very much. I've tried entering "IF" at the beginning of my formula, but it just gave me error messages.
