How do I get my counter to work? This was over my director's head. Please include explanation, and feel free to comment.

CONFUSION: I'm confused about the MovieClip container in as3. public class NumbersView extends MovieClip, so that seems to be a container. That may not be the problem, but that's where I got lost.

CODE http://videodnd.weebly.com/
The working version of this code is fantastic. My code bellow is an attempt at revising it. The source has been adapted from various smart people. It's a work in progress

LIBRARY OBJECT
'vertical number column' Name: mc-NumberImage
Class: NumberImage

D E S C R I P T I O N

COUNTER: formatCount needs to get passed to Tweener

STAGE: for loop, sets up children to be added to the stage NumbersView becomes item, item array adds children to stage

TWEENER: advances the vertical number column every time the count fires adds and removes

- Learning
- Benifit in simplifying the classes and putting it in one FLA
