Server redirect into a flash movie


I have a flash movie which when I press a button will call a url and append parameters to it based upon values in the form (this is working fine). This submits to a server side page which processes an email and then does a server side redirect back to the page with the flash movie on. Is there anyway I can specify which part of the flash movie to go to. I would like to be able to pass parameters into the movie so I can go to a specific frame and display a thank you page.

Thanks for any help

Solved it a different way we have used loadVariablesNum and passed a url with the parameters on the end to the page where we can grab them and then load a set of variables and use these to redirect the movie.
