passing functions using array and buttons as3?

I have been searching for an answer to my actionscript 3 problem... I'm new to the community and actionscript so please bear with me. I am using a array to store my data and have six movie clips I have wrapped in separate functions. Each function will use a tween animation property for each movie clip. I have two buttons (nextBtn & prevBtn) and I want to call each function using the nextBtn and the array. Thank-you for your reply. Here is my code:

   stop();
   var animArr:Array = [anim1, anim2, anim3, anim4, anim5];

    var blindsObj:Object = {type:Blinds,
                        direction:Transition.IN,
                        duration:2,
                        easing:Strong.easeOut,
                        numStrips:10,
                        dimension:1};

    //  REGISTER your buttonListeners */
    nextBtn.label = "Play";


    //  ****  ANIMATION FUNCTIONS */
    function anim1()
    {
    var myTween:Tween = new Tween(panel_2, 
    "x", 
    Elastic.easeIn, 
    650, -22, 2, true);
    }

    function anim2()
    {
    TransitionManager.start(panel_3, 
    {type:Fade, direction:Transition.IN, duration:9, easing:Strong.easeOut});   
    }

    function anim3()
    {
    TransitionManager.start(panel_4, 
    {type:Fly, direction:Transition.IN, duration:3, easing:Elastic.easeOut,     startPoint:9});
    }

    function anim4()
    {
    nextBtn.enabled = false;
    panel_5.alpha = 1.0;// 100% (reset alpha)
    var transition:Transition = TransitionManager.start(panel_5,blindsObj);
    transition.addEventListener("transitionInDone", transition_transitionInDone);
    }

    function anim5()
    {
    var myTweener:Tween = new Tween(panel_6.txtBox, 
    "x", 
    Elastic.easeIn, 
    -1850, 225, 2, true);
    }
    ////////////////////////////////////////////// END ANIMATION FUNCTIONS */


    //  ****  transition the blindsObj tween */
    function transition_transitionInDone(e:Event):void
    {
    nextBtn.enabled = true;
    panel_5.alpha = 0.5;// 50%
    }


    for ( var i=0; i < animArr.length; i++ )
    {
    nextBtn.addEventListener( MouseEvent.CLICK, nextHandler );
    //prevBtn.addEventListener( MouseEvent.CLICK, prevHandler );
    }

    //  ****  FUNCTION TO MOVE THE MOVIECLIP FORWARD */
    function nextHandler(e:MouseEvent):void
   {
        trace( "you clicked " + e.target.name );
        panel_2.MovieClip = animArr[1]; 
    }
