Access 2019 - Using Temporary Variables see if an event has occurred
This video shows how to set a temporary variable when a button has been clicked to influence the behavior of another button. This case stops a record from being cleared from a form if the record has not yet been printed. The TempVar is set to Y when the print button is clicked and the Close Record button checks for this value before clearing the form data. If the TempVar is not set to Y, the Close button runs a message box to prompt the user to print the record.
