var tweenX:Tween = new Tween(football_mc, "x", Regular.easeOut, football_mc.x, x2, 3, true);

//Tween animation in y-axis
var tweenY:Tween = new Tween(football_mc, "y", Regular.easeOut, football_mc.y, y2, 3, true);

//Add Listener to tweenX
//Listen when the motion of tweenX FINISHED
//Will call moveMore function when motion of tweenX FINISHED
tweenX.addEventListener(TweenEvent.MOTION_FINISH, moveMore);


function moveMore(event:TweenEvent):void {

//Display message in Msg Box
