ActionScript 3.0 :: Movie Won't Playback

I've created a "flashloop" for a client, but it won't loop. I've done it in AS3, and all the code is on the first frame of the maintimeline, which does not have a stop() on it. I've published it to loop, and made sure the HTML has the loop = true value, but it doesn't loop. The SWF doesn't even loop when played in the Flash Player.
 
addChild(title1);title1.x = 840;title1.y =  650;title1.text = "Identity Management";
timer1.addEventListener(TimerEvent.TIMER, beginIntro);timer1.start();
function beginIntro(event:TimerEvent):void{    trace("beginIntro initiated");    addChild(slatsR);
 
This is the code at the ending:
 
function pauseRestart(event:TweenEvent):void{    timer20.addEventListener(TimerEvent.TIMER, fadeLogo);    timer20.start();}
function fadeLogo(event:TimerEvent):void{    fadeOutLogo = new Tween(logo,"alpha",None.easeNone,1,0,3,true);    timer20.removeEventListener(TimerEvent.TIMER, fadeLogo);    timer20.stop();}
