The Join Table can display fields from both of the other tables related to a student and a university.
Thanks for your reply.
If I have university A with students 1, 2 and 3
If I have university B with students 4, 5 and 6
Student 5 is also with university A.
How can I setup a layout to add a record in the jointable. I know how to use a portal to add a student to a university or a university to a student. But I want to join a existing student to a existing university.
Use a portal to the join table instead of a portal to the "other table" on the "far side" of the join table in your many to many relationship.
