Script Only Stack Behaviors and Nesting

Actually, do you mean you want to set the script locals for the behavior 
object itself? You can do that, but it will only apply to that 
particular control. The magic word is "this me" : "set the sLocal of 
this me to xxx".

If you want the script locals of the behavior object to be shared for 
every other object that uses the behavior, you need global variables. 
Behaviors act like they are the actual script of an object. Setting a 
script local for button 1 wouldn't share that value with button 2.
