Loader gets stuck, have to right click then play

[lukegould]

i'm pretty new to this, just piecing together AS2.0 from youtube vids and forums,
here's my site, http://www.firstoffenders.tk i've got mates to look and they've said no problems but usually i click enter, then the loading bar will appear at one position (not moving) at say 30% and doesn't proceed any furthur (pauses playback). If i then right click and click Play then all is well and no probs, but this is not ideal.

my script for the loader is:

stop();
mc_loadingbar._xscale = 1;
var loaded = _root.getBytesLoaded();
var total = _root.getBytesTotal();
var percentage = Math.round(100/total*loaded);
mc_loadingbar._xscale = percentage;
if (loaded >= total){
gotoAndPlay(3);
}

its on a separate layer labelled actions.

any help would be really appreciated please! hope the problem is obvious
