Sorry, I did the spheres thing in down time at work and don't have a copy on my PC at home - here's the setup though, hope it helps...
The script I gave you earlier lives on each one of the control clips. They set _parent.size which is what governs the main sphere. The sphere has some code on it (can't remember exactly what I did but it will be similar to this)...
onClipEvent(enterFrame){
_xscale=_yscale=_parent.size;
}
That should get you up and running.
