passing values from 2 flex movies

I have a flex compiled swf module inside my flex program I just need to pass it some values like 开发者_如何学编程I do it when I use chat.swf?username=john : that works !

I tried it with flex swfLoader and Image

SWFLoader source="../bin-debug/chat.swf?username=john"

Image source="../bin-debug/chat.swf?username=john"

This does not work: these values are not passed !

what is the simplest way to do it ?

Regards

Load the swf up and set the variables on it normally like it was a regular object.
