Need some serious help on preloader

Hi, I was using Senocular’s linking external flash preloader, well…it does link to the external flash animation but the preloader just wouldn’t show up. It seems the attactMovie is not working properly on mine stuff. I wonder whats gone wrong?

code:

_root.intFace.M_AP.onPress = function(){
_root.contents.gotoAndStop(26);
startPreload(“Aboutproject.swf”);

}
_root.intFace.M_AS.onPress = function(){
_root.contents.gotoAndStop(26);
startPreload(“Aboutproject.swf”);

}

// this function begins preloading a swf url
function startPreload(url){

_root.contents.empty.loadMovie(url);
attachMovie(“cyclist”, “preloader_mc”, 500, {_x:575, _y:565});
trace(preloader_mc._x);

onEnterFrame = preloadContainer;

}

Really need some help here since the assignment is due next week, any response will be appreciated. Thnx
