AS3 Error:1010

Here’s my code: I’ve truncated all the unnecessary functions and variables.


package  {
		
	import ... ;
	
	public class DocumentClass extends MovieClip {		
		
 		//
		// Containers
		//		
		private var interactiveContainer:MovieClip = new MovieClip();	// container for all buttons
		
		public function DocumentClass() {
			...
		}
		//
		// showing the content of selected object
		//
		private function updateComment(comment:String):void {
			trace(comment);		//trace perfectly what I need, on the output
			//interactiveContainer.alpha = .20;		//works in targeting the whole container
			
			//FAILS I need comm, which is inside interactiveContainer, that has a textbox labeled desc to say what comment says
			interactiveContainer.comm.desc.text = comment;
		}
		//
		// Adds a comment to bottom of the screen
		//
		private function addComment():void {
			var comm:commentMc=new commentMc();// constructs a new plant
			interactiveContainer.addChild(comm);// adds the plant
			//addChild(comment);
			comm.x=20;
			comm.y=470;
			comm.desc.text = "";
		}
		//
		// Mouse over obj
		//
		function onFishOver(event:MouseEvent):void{
			event.target.setSpeed(0);
			event.target.fishIMG.alpha = 1;
			//var mc:MovieClip;
			//mc = event.target.parent;
			//trace(fishHolder.numChildren);
			//trace(event.target.name);
			fishHolder.setChildIndex (fishHolder.getChildByName(event.target.name), (fishHolder.numChildren - 1));
		
			//Code that is being problematic.
			updateComment(event.target.getFishDesc());
			
			//event.target.frameState(2);
			//trace(fishContainer.getChildAt(1));
		}
	}
	
}


My artistic attempt to resemble what I’m trying to achieve…

How do I address the desc.txt portion to update itself (which is inside the interactiveContainer) according to what the “fish” object holds after moving it right on top of it?
