How to control a loaded flash movie? Please help!!!

Question

Hello everyone
I'm creating a web site with multiples swf files, the navigation is controlled via drop down menu, i have resolved the script for the drop down menu main buttons and i need to control the timeline of the movies loaded with the drop down menu main sub buttons to navigate into specific frames
this is what i got:
stop();
var myrequest:URLRequest=new
URLRequest("HomeSonny.swf");
var myloader:Loader=new Loader
myloader.load(myrequest);
stage.addChild(myloader);
//main buttons
menu.nosotros.addEventListener(MouseEvent.CLICK, clickmouse);
//menu.islas.addEventListener(MouseEvent.CLICK, clickmouse);
//subButtons
menu.historia.addEventListener(MouseEvent.CLICK, subMenu);
//event listener main buttons
function clickmouse(evt:MouseEvent):void {
     trace("click")
     myloader.load(new URLRequest("swf/"+evt.target.name+".swf"));
//listener loaded movie
myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, subMenu);
//event listener sub buttons control loaded movie
function subMenu(evt:MouseEvent):void {
     trace("clickSub")
     var mycontent:MovieClip=evt.target.content;
     mycontent.gotoAndStop("historia");
the problem is when i click the drop down menu sub button, does not go to the label frame of the loaded swf fil.
What am i doing wrong?
sample in the file....
thanks for watching.........

See code and comments below. I don't guarantee that it will fix all your troubles though - you have big flaws in the logic:
stop();
// declare this var here so that is accessible
var mycontent:MovieClip;
var myrequest:URLRequest=new URLRequest("HomeSonny.swf");
var myloader:Loader = new Loader();
// you need to add listener here - before you start loading
// also you shouldn't mix loading with mouse click
myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, onFileLoad);
myloader.load(myrequest);
// since your content changes - you shouldn't add it here
// stage.addChild(myloader);
//main buttons
menu.nosotros.addEventListener(MouseEvent.CLICK, clickmouse);
//subButtons
menu.historia.addEventListener(MouseEvent.CLICK, subMenu);
function onFileLoad(e:Event):void {
     // remove previous content
     if (mycontent) {
          removeChild(mycontent);
          mycontent = null;
     mycontent = evt.target.content as MovieClip;
     addChild(mycontent);
function clickmouse(evt:MouseEvent):void {
     trace("click")
     myloader.load(new URLRequest("swf/"+evt.target.name+".swf"));
function subMenu(evt:MouseEvent):void {
     trace("clickSub")
     mycontent.gotoAndStop("historia");
