Advance from current position, Tweener, AS3

I want my animation to advance 120 pixels each time. Instead, my animation goes back to the bottom, rather than advance from it's new position. It assumes a new position, but always go back to the bottom first. How do I get my animation to advance from it's current position each time?

GOAL

I want my animation to advance 120 pixels from current new position, and repeat after ten.

PROBLEM

Animation resets to bottom each time, before advancing. I don't if it's a Tweener problem, how I set up my loop, or something unrelated. If you can give me an example of how to modify this code, I would be appreciated.

Tweener http://hosted.zeh.com.br/tweener/docs/en-us/

I kind of was able to get your code to animate items and I saw that each time the items animated they restarted at their position, here is what I changed to get them to move up from where they are currently positioned:

original:

if (_listItems[i].y < 0) _listItems[i].y = numHeight;
Tweener.addTween(_listItems[i], { y:newY, time:3 } ); 

changed to:

//if (_listItems[i].y < 0) _listItems[i].y = numHeight; //get rid of this line
Tweener.addTween(_listItems[i], { y:_listItems[i].y+newY, time:3 } ); 

For the looping portion of this you can use a timer, here is what I put together as an example for you. It's probably not perfect, but hopefully gives you an idea for what you want it to do:

package   
{ 
    import flash.display.DisplayObject; 
    import flash.display.MovieClip; 
    import flash.utils.Dictionary; 
    import flash.events.Event; 
    import flash.events.TimerEvent;
    import caurina.transitions.Tweener; 
    import flash.utils.Timer;

public class NumbersView extends MovieClip 
{ 
    private var _listItems:Array; 
    private var previousNums:Array; 
    private const numHeight:int = 120; 
    var t:Timer;

    public function NumbersView()  
    { 
        _listItems = new Array(); 
        previousNums = new Array(); 
        //Tweener.init();

        var item:NumberImage; 
        for (var i:Number = 0; i < 9; i++) { 
            item = new NumberImage(); 
            addChild(item); 
            item.x = i * item.width; 
            _listItems.push(item); 
        }

        t = new Timer( 1000 ) //1000ms = 1 second intervals
        t.addEventListener(TimerEvent.TIMER, onTimer);
        t.start();

    } 

    public function onTimer( e:TimerEvent):void {

        //this will run every 10th time firing
        if( t.currentCount % 10 == 0 ) {
            //do something to reset the listItems
            for (var i:Number = 0; i < _listItems.length; i++) { 
                _listItems[i].y = numHeight;
            }
        }

        //do your setTime function, I just randomly called it with random numbers
        setTime(Math.round(Math.random()*234567).toString());
    }

    public function setTime(number:String):void { 
        var nums:Array = number.split(""); 
        trace("$number = " + number);
        for (var i:Number = 0; i < nums.length; i++) { 
            if (nums[i] == previousNums[i]) continue; 
            Tweener.removeTweens(_listItems[i]);    

            //newY:int = -numHeight;
            var newY:int = int(nums[i]) * -numHeight;
            trace("newY = " + newY);
            trace("currY = " + _listItems[i].y);                

            Tweener.addTween(_listItems[i], { y:_listItems[i].y+newY, time:3 } ); 
        } 
        previousNums = nums; 
    } 
} 
}
