A script handler you can implement to override standard MoneyWorks behaviour.
Automatically called: When a cell in an editable list (such as the detail line entry list) is about to be exitted. Row and column numbers are zero-based. Return 0 if the cell value is not acceptable: this will keep the focus in the cell. IMPORTANT: If you do this you should provide an explanation to the user via an alert or coachtip. Users will be very unhappy if they don't know why they can't exit a cell!
Use for: Validating the content of a cell.
Return value: Boolean
