In backend, there are four tables:
Category
SubCategory
Class
SubClass
All four tables are linked. The AutoID in Category is saved in SubCategory. The AutoID in SubCategory is saved in Class. And so fourth..
When I open the backend, I get the plus symbols to expand Category to view SubCategory. The plus symbol to expand Class to view SubClass.
Unfortunately, I cannot get these relationships to work in the frontend. When I open Category in the front end, I don't get the plus symbols to expand. I've tried everything I know to try. I defined relationships in the backend before linking to the front end. I tried establishing the relationships in the front end but even that doesn't work.
Any ideas??? Thx!
