my flash swf cant detect event.COMPLETE - actionscript-3

Question

i have a flash file, containing 2 scene.
first scene have continuous looping of random selected external flv file, using flvplayback.
second scene contain code for 2 external swf file, play after another. continuously.
however, it seem dont work for the second scene. it just wont get into the function.
here, i also paste down actionscript code for scene 2.
stop();
var myLoader:Loader = new Loader();
var url:URLRequest = new URLRequest("loader.swf");
myLoader.load(url);
addChild(myLoader);
stage.loaderInfo.addEventListener(Event.COMPLETE,playnextswf);
function playnextswf(event:Event):void{
trace("in function");
removeChild(myLoader);
var myLoader2:Loader = new Loader();
var url2:URLRequest = new URLRequest("intro.swf");
myLoader.load(url2);
addChild(myLoader2);
}
EDIT
i do some editing, by change this line of code:
.addEventListener(Event.COMPLETE,playnextswf);
to
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,playnextswf);
it seem to jump into function, but with error.
in function
in function
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I think you are looking more for:
var myLoader:Loader = new Loader();
var url:URLRequest = new URLRequest("loader.swf");
myLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, playnextswf );
myLoader.load(url);
addChild(myLoader);
You attached the listener to the stage loaderInfo which works a little differently, from adobe:
The LoaderInfo class provides information about a loaded SWF file or a
loaded image file (JPEG, GIF, or PNG). LoaderInfo objects are
available for any display object. The information provided includes
load progress, the URLs of the loader and loaded content, the number
of bytes total for the media, and the nominal height and width of the
media.
As we discussed in chat you are looking for something more like this:
var myLoader:Loader= new Loader();
myLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, onLoaderComplete );
myLoader.load( new URLRequest( "loader.swf" ) );
var myLoaderSwf:MovieClip;
function onLoaderComplete( e:Event ):void {
trace( "first swf loaded" );
myLoaderSwf = e.target.content as MovieClip;
addChild(myLoaderSwf);
myLoaderSwf.addFrameScript( insert frame number, loadNextSwf );
myLoaderSwf.gotoAndPlay(2);
}
function loadNextSwf():void {
trace( "removing currently loaded swf -- loading next swf" );
removeChild( myLoaderSwf );
myLoader = new Loader();
myLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, onIntroComplete );
myLoader.load( new URLRequest( "intro.swf" ) ); //change this to intro.swf
}
function onIntroComplete( e:Event ):void {
trace( "intro swf loaded" );
myLoaderSwf = e.target.content as MovieClip;
addChild(myLoaderSwf);
}
