The below is my code for trying to clone the MovieClip and it doesn't work. We should see two cirles if the codes is working correctly.
/*The original MovieClip*/
var circle:MovieClip = new MovieClip();
circle.graphics.beginFill(0xAA0022);
circle.graphics.drawCircle(40, 40, 40);
circle.x=10
addChild(circle);
/*CLONE the MovieClip - IT DOES'T WORK FROM HERE DOWN*/
var cloneCirle:MovieClip = new MovieClip();
cloneCirle=circle
cloneCirle.x=60
addChild(cloneCirle);
