Actionscript 3.0 :: Dynamic Building Arrays With MovieClip Names?

In the AS2 days you could create an array and add a bunch of Mc names to it like so

Code: Select allarray("clipA","clipB","clipC", etc..)

Then you could use this array to reference clips dynamicly or on stage to do stuff.I was trying to do the same with AS3 but came across a problem I've not found an answer to yet. I created the following code:

Code: Select allvar letterArray:Array=new Array("A","B");
var buttonArray:Array = new Array();
//

[code]....

Now with the line:

Code: Select allvar currentButton:MovieClip = buttonArray[i];

I get: Type Coercion failed: cannot convert []@369e8581 to flash.display.MovieClip.but if I remove that line, it works. My problem is that I need to make it a "var" of type movieclip before I can assign a listener to it. Why can't I build an array of movieclip names using:

Code: Select allbuttonArray.push(["button"+letterArray[i]]);

I have seen arrays in the past that contain:

Code: Select allarray(mc1,mc2,cm3, etc...)

but notice that it's just using the name of the clip and not array("mc1","mc2","mc3", etc..)
