Add ease effect

I made a horizontal scroll bar using kirupa file for a vertical one, but i need to add an ease effect on the movement of the movieclip. Any ideas. The code i use follows.


scrolling = function () {
	var scrollWidth:Number = scrollTrack._width;
	var contentWidth:Number = contentMain._width;
	var scrollFaceWidth:Number = scrollFace._width;
	var maskWidth:Number = maskedView._width;
	var initPosition:Number = scrollFace._x=scrollTrack._x;
	var initContentPos:Number = contentMain._x;
	var finalContentPos:Number = maskWidth-contentWidth+initContentPos;
	var left:Number = scrollTrack._x;
	var top:Number = scrollTrack._y;
	var right:Number = scrollTrack._width-scrollFaceWidth+scrollTrack._x;
	var bottom:Number = scrollTrack._y;
	var dy:Number = 0;
	var speed:Number = 10;
	var moveVal:Number = (contentWidth-maskWidth)/(scrollWidth-scrollFaceWidth);
	
	scrollFace.onPress = function() {
		var currPos:Number = this._x;
		startDrag(this, false, left, top, right, bottom);
		this.onMouseMove = function() {
			dy = Math.abs(initPosition-this._x);
			contentMain._x = Math.round(dy*-1*moveVal+initContentPos);
		};
	};
	scrollFace.onMouseUp = function() {
		stopDrag();
		delete this.onMouseMove;
	};
	if (contentHeight<maskHeight) {
		scrollFace._visible = false;
	} else {
		scrollFace._visible = true;
	}
};
scrolling();

Any help will be apriciated

well, the basic formula for ease is like:


obj._x += (lockX-obj._x)/easeAmount;//or
obj._y += (lockY-obj._y)/easeAmount;

something like that, figure it out;)
