[RESOLVED] referring to an instance with a variable??

[LukewarmSteak]

i can't really explain what I'm trying to do here... but here it goes
i'm trying to access an instance by using a variable but when i try to manipulate a property to the instance (by referring to it with a variable) it only recognizes it as a string... for instance... (pun intended??)

public var prevbutton:String = "btn1";

trace(["page"+prevbutton]);
// which traces - pagebtn1

trace(pagebtn1);
// which traces the instance class - [object btn1pageclass]

I want to call the instance by using a variable... how do i do this?
