How should I populate the class sign ups table? With what fields? I have the classID as the primary key, but it's also the primary for the classes table. Then I have memberid and classname, what else do I need and how is any of this going to make it possible for a child to sign up and be shown as a memberid of many without taking up numerous fields to accomplish all members signed up for a single class to show up? I dont even know what I'm asking anymore. How do I do this table and what relationships?
