Hello, @bubbleweb5151! I did a test here by creating a car table, with two fields, as I will send you some prints. I believe you have reversed it, because the car has a customer, because the customer registration comes before any purchase of a car, right, or of any product, because the product needs to have someone for it to be linked to something or someone. In my opinion of course, I am just a mere beginner too. I will send you the prints. You need to work with nested reapeat groups.
