>This isn't the problem. The problem is if I change the data in the textbox and I don't TAB or Enter and choose the save button on the toolbar the change is not saved.
Colin,

Inthe beginning of the code in the Save button put this ;

 IF PEMSTATUS("_SCREEN.Activeform.ActiveControl.SetFocus",5)
    _SCREEN.ActiveForm.ActiveControl.SetFocus()
 ENDIF

That will force the current control to loose and then regain focus thereby updating its controlsource.
