Problem with timeline

I have a problem with my new website. I insert to timeline modified to movie clip intro. First of all I want close automatically intro. Second of all I want delay start webpage after intro. I tried many options, but without good result.
Below I show my as2 in frames.

First Frame:

Actionscript Code:

container_mc.loadMovie("myintro.swf");

(stop);

isstopped = true ;
_root.onEnterFrame = function() {
trace(secondScene);
if ( isstopped ){ delete this.onEnterFrame; }
fscommand("quit") {
window.close ();
}

}
_root.gotoAndStop(2);

Second Frame:

Actionscript Code:

Stage.align = "TL";
Stage.scaleMode = "noscale";
Stage.showMenu = false;
_root.preloader._width = 0;
_root.onEnterFrame = function ()
{
    _root.preloader._y = Math.round(Stage.height / 2 - 200);
    _root.preloader._width = loaded / total * Stage.width;
    if (this.getBytesLoaded() == this.getBytesTotal()) 
    {
        __root.preloader._width = 0;
        delete this.onEnterFrame;
        this.gotoAndStop(4);
    }
}
;
stop();

I need a help!!!
