[flash mx] Need password protection help please

I’m trying to create password protection something like this site’s:

I’ve tried looking up tutorials, but all I can find are ones that tell me how to create one password for one movie. What I’d like to do is use one input field and have multiple possible passwords that would take you to their corresponding movies.

Thanks for your help!
