Timeline Seekbar in AS3 - actionscript-3

Question

I'm trying a flash actionscript project to include a custom seekbar for timeline frame navigation. Now i could get dragger moving across the seekbar with respect to the totalframes. But dragging the seekbar brings error. Also i want to include timer to show the minute and seconds passed.
var ratio = 0;
ratio = this.totalFrames/main.line.width;
var go = 0;
var isComplete = false;
var tFrame = this.totalFrames;
var isPress = false;
stage.addEventListener(Event.ENTER_FRAME, drag);
function drag(event:Event):void {
if(main.dragger.x<=main.line.width){
main.dragger.x = this.currentFrame/ratio;
}
}
main.dragger.addEventListener(MouseEvent.MOUSE_DOWN, drag1);
function drag1(event:MouseEvent):void {
main.dragger.startDrag(false, new Rectangle(0, 9.2, main.line.width, 9.2));
isPress = true;
main.dragger.addEventListener(Event.ENTER_FRAME, frame);
}
function frame(event:Event):void
{
trace (this.currentFrame);
if(this.currentFrame < tFrame){
gotoAndPlay(Math.round(main.x*ratio));
}else{
gotoAndPlay(tFrame-1);
}
}
main.dragger.addEventListener(MouseEvent.MOUSE_UP,release);
function release(event:MouseEvent):void {
main.dragger.stopDrag();
main.dragger.removeEventListener(MouseEvent.MOUSE_DOWN, drag1);
}
when i click the dragger to move, it automatically jumps to starting position and also the gotoAndPlay jumps to that position and continuously stays there..

UPDATE
This is an other method found in adobe forum, But this also gives the same dragging problem.
var tl:MovieClip=this;
tl.addEventListener(Event.ENTER_FRAME,enterframeF);
paramF(tl,1,0,tl.totalFrames,slider.line.width); // create a horizontal slider movieclip that contains a track movieclip and a thumbscroll movieclip that do the obvious and have left-sided reg point
paramF(slider,0,1,slider.line.width-slider.thumbscroll.width,tl.totalFrames);
var scrollRect1:Rectangle=new Rectangle(0,0,slider.line.width-slider.thumbscroll.width,0);
function enterframeF(e:Event):void{
slider.thumbscroll.x=tl.m*tl.currentFrame+tl.b;
}
slider.thumbscroll.addEventListener(MouseEvent.MOUSE_DOWN,scrolldownF);
slider.thumbscroll.addEventListener(MouseEvent.MOUSE_UP,scrollupF);
function scrolldownF(e:MouseEvent):void{
tl.removeEventListener(Event.ENTER_FRAME,enterframeF);
slider.thumbscroll.startDrag(false,scrollRect1);
slider.addEventListener(Event.ENTER_FRAME,scrollF);
}
function scrollupF(e:MouseEvent):void{
tl.addEventListener(Event.ENTER_FRAME,enterframeF);
slider.thumbscroll.stopDrag();
slider.removeEventListener(Event.ENTER_FRAME,scrollF);
}
function scrollF(e:MouseEvent):void{
tl.gotoAndStop(Math.round(slider.thumbscroll.x*slider.m+slider.b));
}
function paramF(mc:MovieClip,x1:Number,y1:Number,x2:Number,y2:Number):void{
mc.m=(y1-y2)/(x1-x2);
mc.b=y2-mc.m*x2;
}
