I have a form with a calculated field on it. A-B/A, for example.If A is
0, then I want to tell the user that A cannot be equal to 0 and the
cursor should go back to A until they enter a different value.At this
point, I get a system error about dividing by 0 even before I get the
message I give the user.I would appreciate any help on how to accomplish
this.
