AS3: Using an array with MovieClips

programming flash
1

I am trying to create an image gallery using an Array with MovieClips inside it but I keep getting this error:

TypeError: Error #1034: Type Coercion failed: cannot convert Fullsize_01$ to flash.display.DisplayObject.

Here is the code I made. I know it’s probably something simple but I am pretty new to ActionScript.

var Fullsize_Pic:Array = new Array();

Fullsize_Pic[0] = Fullsize_01;
Fullsize_Pic[1] = Fullsize_02;

addChild(Fullsize_Pic[0]);

Cheers!
