Help with slide bar

I created my own stop, play, pause buttons and slide bar to go along with my movie. the code necessary to make them work is below. It used to work seamlessly… however, it stopped working. the slidebar specifically doesn’t work at all. can anyone take a look at the code below and tell me what you think it’s wrong…?

this is my website, you can go to it and see that the slide bar at the bottom doesn’t work… any help will be appreciated. http://www.dmusseb.com

videoclip.stop();
playing = false;
top = progress.slider._y;
bottom = progress.slider._y;
left = progress.slider._x;
right = progress.bar._width - progress.slider._width;
barlength = right;
this.onEnterframe = function()
{
if (videoclip._currentframe == videoclip._totalframes) {
playing = false;
videoclip.stop();
}
if (dragging) {
frame = Math.ceil((progress.slider._x/barlength)videoclip._totalframes);
videoclip.gotoAndStop(frame);
} else {
frame_fraction = videoclip._currentframe/videoclip._totalframes;
progress.slider._x = (frame_fraction
barlength);
}
}
playbutton.onRelease = function(){
videoclip.play();
playing = true;
};

stopbutton.onRelease = function(){
videoclip.gotoAndStop(1);
playing = false;
};

pausebutton.onRelease = function(){
videoclip.stop();
playing = false;
};
progress.slider.onPress = function(){
dragging = true;
startDrag(progress.slider,false,left,top,right,bottom);
};
progress.slider.onRelease = progress.slider.onReleaseOutside = function(){
dragging = false;
if(playing == true){
videoclip.play();
}
stopDrag();
}
