Since the invoices are positive numbers and the payments are negative you
could just sum the Amount column. =sum(c2:c??)

I need to create a formula that refers to a remaining
balance. The form is a Account Statement and has the
following columns:

Date Transaction Amount Balance
1/2/04 Inv.# 123 89.23 89.23
1/10/04 Inv.# 124 50.87 140.1
1/21/04 PMT -60.00 80.10

Amt. Due ?????


How do have excel automatically calculate the amount
due? Any help would be greatly appreciated.

Thanks!
