I replied to your StackOverflow question. An error in your through model caused the no such table error.
Keep in mind that web pages are only generated once, and then presented to the user. If you want the page to display the cost of the course based on the university you pick on this page in the select box, then you need some javascript to perform a real-time update to your admin page before to display the correct price. There are frameworks available as django apps for doing this.
