I have the code below. It does what I need it to do, but I don't want to allow the user to click twice as it would change the results. I need a sort of a run once thing as long as that window is open.
How can I get the code to stop and not allow it to run if results are already in the textticketfield(29)
Private Sub cmdGift_Click()
txtticketfields(29).Text = FormatCurrency(CCur(txtcustomerfields(17).Text) - CCur(txtticketfields(20))) + CCur(txtticketfields(19))
txtcustomerfields(17).Text = CCur(txtticketfields(29))
