Pre loader dosent seem to be working please help

Hi I have a site at

www.freshlemon.co.uk/ppm/intro.html

As you can see when page firt appears the pre loader appears, but it doesnt fill the loader bar to 100% and carrys on playing the movie, however when it starts playing, it wownt let me click sip intro as the page is stil loading, can someone please explain how i can get the pe loader to work so the whole movie finishes loading before it plays the intro? the code i have for the pre loader is this: (the code is placed on the preloader mc

onClipEvent (enterFrame) {
loading = _parent.getBytesLoaded();
total = _parent.getBytesTotal();
/* Your loadbar is 103 pixels big, so it will fill up
103 pixels. /
percent -= (percent-((loading/total)93)).25;
per = int(percent);
/
Make the loadbars width match the percent.
EG. 1% = 1 pixel. */
loadBar._width = per;
// If the percent loading is over 99%.
if (percent>99) {
// Where the movie goes after loading is done.
gotoAndStop(1);
}
}
