I’ve been reading up on LocalConnection, LoaderInfo, and SharedObject but can’t seem to get anything to work. There must be a simple way for a preloader to pass a variable to the swf it loads.

I’ve got a preloader swf that loads my main swf that gets it’s content from a xml file. I would like to pass the location of the xml file as a string with a flashvar to the preloader that then passes the location variable to the main swf. Here’s my code for the preloader:

```auto

var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest("visitor_map2.swf"));

function loop(e:ProgressEvent):void {
    var perc:Number = e.bytesLoaded / e.bytesTotal;
    percent.text = Math.ceil(perc*100).toString();
}
function done(e:Event):void {
    removeChildAt(0);
    percent = null;
    addChild(l);
}

```

Doesanyone know of a simple way for me to pass 1 variable form 1 swf to another? Thanks!
