Rotation Around A Common Center onEnterFrame question

Hi

http://www.kirupa.com/developer/actionscript/rotation_center.htm
I’m using this code i made some changes like changing the array for a xml.
In some part i put a button to stop the movement and i used

delete theScene.onEnterFrame

and it works perfectly, but then i want to return with another button to the movement. and i can’t make it work

i tried

theScene.onEnterFrame
this.onEnterFrame

i hope someone could give me a hint on this.

thanks in advance
