Hey, Thanks for replying. I tried what you said but It's still giving the error. I've also updated the StackOverflow question with updated code. One more thing, as you said about JavaScript. I think I won't be needing it on that page because this *through *models seems to be the solution to my problem (once that table error is resolved). Because I think I can manually add "fees" through that additional field (by Choosing the university, and course from the drop down).
