Controlling loaded swf from main timeline

Hello,

I'm working on loading external swf files for ios. I am able to load the swf files and set them to visible or invisible in different frames. I am having trouble controlling the loaded swf files from the main timeline. Specifically, I would like to have a button on the main timeline, that when clicked will move a loaded swf to frame 1.

Here is a code that loads one swf file:

var myLoader1:Loader;

var loaderContext1:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);

if(myLoader1 == null)

{

          myLoader1 = new Loader();

          addChild(myLoader1);

}

myLoader1.load(new URLRequest("folder/file1.swf"),loaderContext1);

myLoader1.visible = true;

backbutton.addEventListener(MouseEvent.MOUSE_DOWN, backbutton1);

function backbutton1(myEvent:MouseEvent):void {???????????? myLoader1.gotoAndStop(1);}  (this line does not work)

(Once I load file1.swf, within the file1.swf I click a forward button to move to different frames. My question is: how do I code the 'backbutton' on the main timeline so that it causes the loaded file1.swf to go to frame 1?)

Thank you for your help.
