Consider putting the ListOfForm.FormID as a tag value on each applicable command button on the menu form. On form opening, loop through the controls looking for Type acCommandButton and get the tag value. Look up the userID and FormID in ListOfForm and get the yes/no value for that user-formID combination. If yes, enable the control; if no, disable. Maybe someone else has a more elegant idea...
The more we hear silence, the more we begin to think about our value in this universe.
