ActionScript 3.0 :: Animation On Banner - Catch Trash Falling Down On Stage

I'm trying to make a banner with a small game where you control a trash can, and you try to catch some trash falling down the stage. Also I got a dynamic text field on my stage called "tekst", where I want my counter to be shown. At last I'm trying to make a if sentence saying that if etc. counter<10 go to url. When I run it now, the trash is moving all right, but I can't get the hitTestObject to work, its saying that hitTestObject is not a function? How to export my counter to the text field on the stage.

Code:
Mouse.hide();
var trash:trashcan = new trashcan;
var banan:Array = new Array();
var cskod:Array = new Array();
var velocity:Array = new Array();
var counter:int = new int();
[Code] .....
