I'm helping out a friend of mine in writing a VB program. Purpose of program: Track the times of phone calls from different depts, and keep an average of those times, as well as if the caller is transfered at the end of the call or not.

Everything is going good except we want to be able to remove the last call entered if we accidentally add a call to the wrong dept. Just how do we do this?

Assuming there is only 1 call available, we keep getting a divide by 0 error when we try to remove it.
Any and all help will be appreciated. Thanx
