Hi I need help figuring out a formula for a running
balance. I have 3
columns one called deposits, another called petty cash
disbursements and
another called expenses. I want to be able to know how
can I get the total
amount of money that I have on an account even though I
keep on entering
different dollar amounts at all times. I know that the
formula =A39-B39 is
giving me the amount for the first two columns, but I
don't know what to do
for the third column.

I would really appreciate it if someone can help me out.
Thanks.
Jackie
