I wanted to make a pop up message box that warns the user if they make a change to an existing record it asks them if they are sure they want to change 1234 to 5678 (for example). If they click yes, then it will keep the changes. If they click no, it goes back to what it was. I want it for the entire form. If a new record is being entered then I do not want this message box to show up. Does anyone know the code for this? Can I just put the code in before update event?
