Help with proper set up of my actionscript.

Question

http://goodielcreative.com/test.html
Above is a link to the project I am working on.
I have a couple issues with it but the one I am currently concerned with is proper set up of actionscript.  To be more specific the Dynamic text field functionailty on this page.
It works fabulous when you click on a graphic to the lower right of the screen it spits out the correct information and here is the as file /code that gets it to work :
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class WoodBaluster extends MovieClip {
var balusterNumber:String;
var balusterName:String;
var eventName:String;
var stringManip1:String;
public function WoodBaluster() {
this.buttonMode = true;
this.addEventListener(MouseEvent.MOUSE_DOWN, onDown);
private function onDown(event:MouseEvent):String {
MovieClip(root).stairStage_mc.wood2Balusters1_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters2_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters3_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters4_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters5_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters6_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters7_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters8_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters9_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters10_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters11_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters12_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters13_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters14_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters15_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters16_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters17_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters18_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters19_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters20_mc.gotoAndStop(event.target.name);
MovieClip(root).stairStage_mc.wood2Balusters21_mc.gotoAndStop(event.target.name);
eventName = event.target.name;
stringManip1 = eventName.substring(0, eventName.indexOf("_")); //get the part before the _
balusterName = stringManip1.substr(0,2) + "-" + stringManip1.substr(2); //insert a - between first two chars and the remainder
if(MovieClip(root).stairStage_mc.currentFrame == 1)
balusterNumber = "Two Baluster";
else if(MovieClip(root).stairStage_mc.currentFrame == 2)
balusterNumber = "Three Baluster";
MovieClip(root).selection_txt.text = "Wood, Post to Post, ";
MovieClip(root).selection_txt.appendText(balusterNumber + ", ");
MovieClip(root).selection_txt.appendText("using " + balusterName + " Baulsters");
return balusterName;
You start off in two baluster and then click a baluster and the text field populates. Works like it is supposed to. same thing if you click on three baluster and then click a graphic of a baluster it populates the text field correctly.  How ever my issue is clicking on two or three baluster buttons should also populate the text field where "Two Baluster" or "Three Baluster" is not just after the graphic of the baluster is pressed.
I have tried a number of different thing but have run into a brick wall. Could be I am so new at it I am over thinking it or I just don't have the skill set to think of a solution.

Answer 1

I was trying to figure out a way to wrap the setting of all of the dynamic text field into this as file I could not figure out how to. As you stated it only works with the WoodBaluster instances.
Thanks.
