I am trying to allow user to enter date (MMDDYYYY) in a form but I want Access to automatically populate the last day of the month when the user enters the Month (MM) and Year (YYYY) e.g user enters 02/2003 and Access returns 02/28/2003. Can this be done through the input mask of the field, or would it require VBA code? Either way if someone can assist I would greatly appreciate it.
