[AS]  
class test extends MovieClip {  
private var butnPath;

function test() {  
butnPath = this.cool\_button  
}  
}  
[/AS]  
I assign this custom class to a MC containing a button with a instance name ‘cool\_button’.  
This code gives a me a compile error of ‘variable cool\_button not defined’, what i am trying to do is reference something that is in the MC itself. The only solution i have found is to name the var the same as the instance name you are trying to reference.
