Passing a variable with URLRequest

Hello all,

I’m desperately trying to pass a variable from as3 to as2 using URLRequest. I’ve done this before this way for some reason i can’t anymore.
Here is what I’m doing:

var movie:String=“mymovie.swf”;
var mLoader:Loader = new Loader();
var mRequest:URLRequest = new URLRequest(“swfloader.swf?m=”+ movie);
mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);

in my main file and the file swfloader.swf is an as2 file and inside I do:
var movie:String=_root.m; //get the movie name passed

loader.loadClip(“tutorial_movies/”+movie, container);
all my loading process to load mymovie.swf

But I get a Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found. in my main file. If I remove the “m=”+ movie" from the url request then i don’t get the error

Please help,

Thank you!
