Hi Diana ---

A good point. If in a situation where you are explicitly locking tables or other "hard" save routine at the end of an edit (ala FP2.6 and earlier), you are 100% correct. In the VFP environment, with optimistic buffering, it's half-dozen of one and 6 of the other....you can always revert the edit as it's not "real" until TABLEUPDATE....

>>Place the calculation in a custom method in the form, such as CalcBalance. In the LostFocus of each control that could affect the balance do a THISFORM.CalcBalance. In the CalcBalance method, calculate the balance and use REPLACE to store it in the balance field in the table. The balance textbox should have a ControlSource of the balance field. After you have done the REPLACE in the CalcBalance method, refresh the balance textbox (THISFORM.txtBalance.Refresh). Also ensure that the balance textbox is disabled.
