Progress Bars

Hi ive pretty much finished my site www.coriolis-effect.co.uk and need some directions to progress bars. I can't find much simple stuff on here (yes im stupid at flash) any tutorials that I may have missed? thanks

Code:

---

//PRELOADER
loadbar_mc._xscale = 1
myInterval = setInterval(preloader, 10);
function preloader() {
        if (getBytesLoaded()>=getBytesTotal()) {
                gotoAndStop(2);
                clearInterval(myInterval);
        }
        loadbar_mc._xscale += (((getBytesLoaded()/getBytesTotal())*100)-loadbar_mc._xscale)/5
        percentage_mc.percentage_txt.text = Math.round(getBytesLoaded()/getBytesTotal()*100)+"%";
}

On the first frame of your FLA make a rectangular movieclip and name it loadbar_mc. Paste this code into the first frame in your actionscript layer.
