I hope this is the correct place to pose this question:

How do I write the formulas for cell C3 and C4 so cells C3 and C4 continue
to derive a cummulative total adding the amounts in column C beginning in
cell C10?

A B C D

2
3 Total credits (C3)=If C10=0, then add it to the
results
currently displayed in cell
C3, but. If C10=<0,
then add 0 (zero) to the
results currently
displayed in cell C3.
4 Total debits (C4)=If C10=<0, then add it to the
results
currently displayed in cell
C4, but, If C10=0,
then add 0 (zero) to the
results currently
displayed in cell C4.

10 08/29 Bill (128.42)
11 09/10 Deposit 1232.00
12 09/11 Food (332.00)
13 10/01 Deposit 1232.00

Is this making sense to anyone but me? I just don't know how to do this.
