The problem I have just encountered is this.
I'm creating a program to track my opinions of movies, actors and studios.
I have a table for the movies, one for the actors, and one for the studios.
I want to be able to enter the cast through a portal in the movie table.
I can create entries in the actors table through my portal from the movie table, but the problem is that if an actor is in more than one movie there is more than one entry in the actors table. Anyone have any ideas as to how I should proceed?
