Input the money amount as a negative, and SUM all of the numbers!
So, if your running total is in Cell Z1, the formula in cell Z1 would be:
A1 = 1500.00 (starting amount)
B1 = -450.00 (deduction)
C1 = 45.00 (deposit)
D1 = -15.00
Z1 would = 1080.00
If this is not what was expected, let us know why this won't work!
It's kind of fun to do the impossible! -Walter Elias Disney
