Hide/get Rid Of A Flash Animation After It Ends?

I'm cooperating with some friends on making the design for a website. I'll be handling all the flash stuff. I'm very good with Actionscript, flash's scripting language. What I'm trying to do is this: in the Home page, I want to add a big flash animation, that goes on top of the normal content (as in a higher layer). The animation will end after some point, after which I want to get rid of it, sort of like a welcome animation, that vanishes off after it ends. This way when someone accesses the website, they'll be greeted to a small non-annoying animation that overlaps the rest of the page, and then they'll be left with the Home.

The problem is this: I don't know how to do it. I don't know javascript. I do know that actionscript is based in javascript. I've been fooling around on some javascript tutorial pages and indeed they are pretty similar, so I'm not entirely helpless.But I can't find what I'm looking for. After a set amount of time, how do I get rid of the flash in the document? Can I eliminate it, make it invisible, unvalidate it or whatever?I thought that instead of having the animation in another page that redirects to the Home, this would be a great opportunity to finally learn how to integrate flash with websites.
