Variables in a loaded swf - HELP

1

[FONT=Times New Roman][SIZE=3]I have “file1.swf” loading “file2.swf” as follows:[/SIZE][/FONT]

 
var myVar:String="hello";
 
var myloader:Loader= new Loader();
addChild (myloader);
var request:URLRequest = new URLRequest("file2.swf");
 
myButton.addEventListener(MouseEvent.CLICK, loadIt);
 
function loadIt(event:MouseEvent):void {
            myloader.load(request);
            myloader.x=100;  //I can see file2 is on top of file1
 }

[FONT=Times New Roman][SIZE=3]How can I get the value of myVar from file1 into file2? Referencing myloader in file2 does not work…not sure where to go from here. Note, both files are in the same web folder. [/SIZE][/FONT]
