Hi, I have created a form which consisted a subform. Actually, this form needs to related to 4 tables, but everytime, when I click on the add record button on the main form, the subform has disappeared. I figured out it is a problem about the table. I tried to create this form with 3 tables, and it worked, however it doesn't work for 4, is there any way i can solve this problem. I need to get it fix by tuesday. Your comments are highly appreciated
