[HELP]Placing external loaded swf on stage

hi, folks,
I am trying to place a swf file on the stage on a specific position.
But i can’t manage to figure out how… I mean, after the event is load (the onCompleteHandler function) i use the addchild, but i reckon i have to create some kind of holder of this SWF(or maybe i’m just all the way outta of it…) Well,
i tried to put the target. coordinate… but it’s no working at all…
I’m kinda noob on AS.
Any help would be great…

function startLoad(imagem:String) { 
var mLoader:Loader = new Loader();
var mRequest:URLRequest = new URLRequest(imagem);

mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);



function onCompleteHandler(loadEvent:Event) {
    event.target.y = 50;
