Xy stage position with dbl nested movies

trying to learn from Ben’s game and already can’t move ball play
to new position on stage, could someone tell me why?

Here is the swf http://sites.google.com/site/0xheartx0/one

and this is the code for the button:

on (release)
{
_root._root.ball.xspeed = 0;
_root._root.ball.ballspeed = 1.100000E+00;
_root._root.ball.yspeed = -2.100000E+00;
_root._root.ball._xscale = 99;
_root._root.ball._yscale = 99;
_root._root.ball.zspeed = -3;
_root._root.ball.realx = 300;
_root._root.ball.realy = 3;
_root._root.ball.xchill = 5;
_root._root.ball.ychill = 20;
startDrag (_root._root.paddle1, true);
Mouse.hide();
tellTarget(_root)
{
gotoAndPlay(2);
} // End of TellTarget
_root._root.paddle2._x = 300;
_root._root.paddle2._y = 60;
_root.ball._visible = true;
_root.paddle1._visible = true;
_root.shadow._visible = true;
_root.paddle2._visible = true;
_root.backbox._visible = true;
_root.paddle2._xscale = 30;
_root.paddle2._yscale = 30;
_root.ball.ydir = 1;
setProperty("", _visible, false);
_root.bluescoreclip.bluescore = _root.ball.score1;
_root.redscoreclip.redscore = _root.ball.score2;
}
