Creating variable number of related records

[msmithtlh]

I have 3 tables involved in this situation.
Individuals with a primary key of individualID. This includes name, address, and other data.
Classes with a primary key of classID. This includes the class name, credits, dates, etc.
The third table - instructors has only two fields - classID and individualID. Both fields are in the primary key. The purpose is to be able to link multiple instructors to one class.

I believe this is correct from the table point of view. I'm stumped on how to handle it on the form where classes are entered. I am guessing I need a subform, but still don't know how to make it work for varying number of instructors. Specific guidance would be greatly appreciated.

I would expect a form bound to the classes table with a subform bound to the junction table (the third table).

Yes, as I said, I expected that I needed a subform. But how do I populate the subform so that a class can have one instructor or three or five? What object type? Do I need a button that says "add another instructor" and what does it do in the background?

A subform in continuous (or datasheet) view will show however many records there are, and will allow a new record to be added at the bottom. The user would be able to add as many or few as they wanted.
