I am trying to create what I would call an if/then formula in Excel 2003. If
someone types the letters PTO into a cell have tat equal zero in the formula.
I have a sum formula of a set of cells I want Excel to be able to add a zero
into the formula if someone types the letters PTO into the cell. My formula
works great until someone types letters into a cell then - of course -I get a
value error in the cell.
