>Roxanne, I have a dbase program which I am attempting to do over in VFP6. I look up the customer and then do some actions, in this case sell items. I have a form that has a total of items, taxes, downpay, tradein, insurance and total. I want to be able to type into the downpay and/or trade in box and have the total automatically recalculated. cTextboxnumeric doesn't respond as i want. Thanks Bob A

Sorry if this late, I've been out of town...

It looks to me like Paul gave you the right idea, trying handling your recalculation in ProgrammaticChange() instead of InteractiveChange()
