Passing a Variable Between ASPX (C#) and Flash

Hello

This is my first venture trying to combine Flash and ASP, although I have come to a snag, I cant seem to transfer the variable from my ASP into my movie.

I have got the variable from the address bar (…?id=1) and I am displaying this in my page (for testing purposes) but Im not sure of the next stage. I tried doing it the same way as you would in php (movie.swf?id=1) but obviously this is not working!

Any help you could provide, or if you could point me in the direction of more info I would be very grateful

Thanks in advance
