Table Relationships
Why do I have the same information repeated in my "courses" table?
I have created a "members/courses" table in order to set up a many to many relationship.
When in the "courses" or "member/course" table, I click on the plus sign, it reveals the members on the related course then there is another plus sign, then another and another etc etc - I must need to change something in the design or relationship set up?

RE: Table Relationships
Hi Emma
Firstly it is better not to have many to many relationships. You you use one to many or many to one.
The problem you are experiencing is most likely related to the many to many relationship, or the is an error in the sql/query.
If you have a many to many relationship you should introduce a third table and make the relationships one to many.
Hope this helps
David
