Button trouble

1

ok… now that we’ve got the array’s figured out im having troubles with buttons
basically all i want is for a movieclip called “slider” to move and adjust its length when i roll over a button called videobtn… here is what i have so far… again, thanks for your help


function moveSlider(xpos:Number, sliderwidth:Number) {
    var xPosT:Tween = new Tween(slider, "x", Regular.easeOut, slider.x, xpos, 2, true);
    var wPosT:Tween = new Tween(slider, "width", Regular.easeOut, slider.width, sliderwidth, 2, true);
}

videobtn.buttonMode = true;
videobtn.addEventListener(MouseEvent.ROLL_OVER, mouseOverVideo);
       
function mouseOverVideo(event:MouseEvent):void {
        trace("videobtnselected");
        moveSlider(12,36);
    }
