I've created a subform within a form based on a query . The subform displays Course information which is held in a Course table created by entering data in a Course form. I want to allow a user to double click the CourseName field in the subform and display the appropriate Course form which created the entry in the Course table in the first place. Also, if the subform contains no records I want to advise a user that, if they have double clicked, their action was inappropriate. I'm not able to write VBA code but can attach any offered to the Dbl Click property of the control. I'm a little more competent with macros so if anybody can advise me regarding the use of appropriate macros (OpenForm, ApplyFilter?) I could probably apply them.
