Sprite y based on mouse position?

So I'm working on my portfolio and I got this problem. The code posted scrolls the sprite "cellContainer" based on the position of stage.mouseY. Perfect.

Problem is that I want stage.mouseY to equal the entire cellContainer height. Kind of like how a small tablet equals a huge monitor. So when stage.mouseY = 0, cellContainer.y = 0 and when stage.mouseY = stage.stageHeight, cellContainer.y = stage.stageHeight - cellContainer.height. Right now, it scrolls, but it takes a while to scroll throught the entire height of cellContainer. I want it to be proportional to stage.mouseY.

Actionscript Code:

private function scrollStart(e:Event):void
        {
            cellContainer.y += Math.cos((-stage.mouseY/stage.stageHeight)*Math.PI) * 10;

            
            if (cellContainer.y > 0) 
            {
                cellContainer.y = 0;
            }
            
            if (-cellContainer.y>(cellContainer.height - stage.stageHeight)) 
            {
                cellContainer.y = -(cellContainer.height - stage.stageHeight);
            }
                
        }

Any help would be appreciated! Thanks!:yarr::yarr:

Okay, no one replied, but I figured it out. If anyone is interested, place this inside ENTER_FRAME:

Actionscript Code:

var containerY:Number = ((stage.mouseY * (stage.stageHeight - cellContainer.height))/stage.stageHeight);
        
            TweenLite.to(cellContainer, .5, {y:containerY});

No one replied, most likely, because this is the non-technical conversation only forum. Please only use the technical forums listed here for technical questions.

Also, do not put it in ENTER_FRAME. TweenLite has its own ENTER_FRAME event. By using ENTER_FRAME, you're having TweenLite reset itself over and over again, even if the mouse isn't moving. Instead, use MouseEvent.MOUSE_MOVE and make sure it's not checking for a mouse movement globally, but only within the bounds of the gallery preview images.
