[HELP] How to use getDefinitionByName?

[VENGEANCE MX]

What I'm essentially trying to do is turn movieclips into spritesheets of themselves, showing all positions of their rotations. I can do this for one MC, but I'm having trouble scaling it up to work on multiple ones.

Here's (the top of) my code:

import flash.utils.getDefinitionByName;

var i:int = 0;

var myMCs:Array = ["Test", "Test2"];

var c:MovieClip;

for (i=0; i<myMCs.length; i++) {
    c = getDefinitionByName(myMCs[i]) as MovieClip;
    addChild(new c());
} 

The problem appears to be with the line addChild(new c());.

It should, in theory, take the list of classes inside myMCs and create an instance of each of those classes.

In other words, I want to dynamically add movie clip instances of Test and Test2 (plus any other ones I add later) to the displayList.

The error I get when I try to compile (btw this is in the Flash authoring environment) is:

1180: Call to a possibly undefined method c.
