Doesnt seem to be so simple

Trying to take the string value of a button passed to a function and add “\_mc” on the end! It just keeps returning undefined? Any ideas?

function openBox(){  
var newName = this.split("\_level0.");  
trace(newName);  
var newName2 = newName.split(“Btn”);  
trace(newName2);  
var newName3 = newName2+"\_mc";  
//\_root[newString].\_visible = true;  
trace(newName3);  
}

It’s not even working when I switch to substr
