I am setting up a payment worksheet in Excel that gives the names in column
A, dates of the different payments in B, C, D, and E, and the total in F.
The total should come out to be $2,500. In column G, I'd like it to show the
amout each person still owes. So, if I place $500 in "A", then "G" should
show $2,000.

What I've done so far is set the worksheet up to add up colums B-E to show
the total in F. Now, how do I get colum F to show the difference still owed?
What formula do I use, and how do I set that up?

Thanks!
