I have a main form with a subform the main form consists of Patient Data and the subform consists of tests each patient has had. There are 6 possibilities. My problem is that if the patient hasn't had any of the tests yet the subform is completely blank so the user is unable to enter any new data. The main form and subform are linked by PatientID. How do I get the subform to display the fields so a new record can be added when none currently exist???
