AS3: need help solving a function problam

Question

Hey, I need your help yet again.
I have a wheel Chair movie clip that I just want to move left and right in a loop, I have this code:
        var wheelChairRightTimer:Timer = new Timer(120,24);
        var wheelChairLeftTimer:Timer = new Timer(120,24);
        wheelChairRightTimer.addEventListener(TimerEvent.TIMER, moveRight);
        wheelChairRightTimer.addEventListener(TimerEvent.TIMER_COMPLETE, startMoveLeft);
        wheelChairLeftTimer.addEventListener(TimerEvent.TIMER, moveLeft);
        wheelChairLeftTimer.addEventListener(TimerEvent.TIMER_COMPLETE, startMoveRight);
        wheelChairRightTimer.start();
        function moveRight(event:TimerEvent):void {
            wheelChair.x = wheelChair.x + 20;
        function moveLeft(event:TimerEvent):void {
            wheelChair.x = wheelChair.x - 20;
        function startMoveLeft(event:TimerEvent):void {   
            wheelChairLeftTimer.start();
        function startMoveRight(event:TimerEvent):void {   
            wheelChairRightTimer.start();
The problam is with the last function "startMoveRight". Without this function the wheel chair goes right and left as intended and than just stops. I added the last function to loop the movment, but after the first round of left and right movment (which works well) it seems as all 4 functions are called together so the wheel chair is stack moving 20 px right and 20 px left.
I know this probably isn't the best way, other ways or just a way to fix this will help alot!

This should do it:
// speed
var vx:Number = 20;
var chairTimer:Timer = new Timer(120);
chairTimer.addEventListener(TimerEvent.TIMER, moveChair);
chairTimer.start();
function moveChair(e:TimerEvent):void {
     wheelChair.x += vx;
     if (chairTimer.currentCount % 24 == 0) {
          // change direction
          vx *= -1;
     e.updateAfterEvent();
