I want to subtract two cells in excel but only if both cells have a value. More specifiaclly in my case the formula in cell E2 is currently =D2-C2 but I only want this to be calculated when D2 has a value. (D2=winnings, C2=stake and E2 = profit/loss. I don't want the profit loss calculated until the winnings cell is completed.)
Can anyone help please?
