Flash + Javascript + CSS = I've created a monster!

1

Greetings

Ok, I had this problem with getting my flash buttons to activate a javascript to change the content of a DIV with a show/hide. I got some help. The weird thing is that the guy who was helping me says it works. I can’t tell because it doesn’t and has errors for me.
He was viewing with: Firefox 2 windows xp, flashplayer 9.0.115
I was viewing with: IE 7 vista home premium CS3 installed
Why?

Here is the site

Here is the AS3:

import flash.external.ExternalInterface;
info_btn.addEventListener(MouseEvent.MOUSE_DOWN, movClick);
function movClick(event:MouseEvent = null):void{
  if (ExternalInterface.available){
    ExternalInterface.call("switchContent", "content2");
  }
}

Here is the javascript:

function switchContent(obj) {
  obj = (!obj) ? 'content1' : obj;
  var contentDivs = document.getElementById('center').getElementsByTagName('div');
  for (i=0; i<contentDivs.length; i++) {
   if (contentDivs*.id && contentDivs*.id.indexOf('content') != -1) {
    contentDivs*.className = 'hide';
   }
  }
  document.getElementById(obj).className = '';
 
 }

And here is the html:

<div id="center">
   <!--start content1 - home -->
    <div id="content1">
      Content for  id "content1" Goes Here    </div>
      <!--end content1 - home -->
      <!--start content2 - info -->
    <div id="content2" class="hide">
    Content for  id "content2" Goes Here    </div>
      <!--end content2 - info -->
      <!--start content3 - work -->
    <div id="content3" class="hide">Content for  id "content3" Goes Here</div>
      <!--end content3 - work -->
      <!--start content4 - contact -->
    <div id="content4" class="hide">Content for  id "content4" Goes Here</div>
      <!--end content4 - contact -->  
    <!--start bottom -->
    <div id="bottom"></div>
      <!--end bottom -->
  </div>
  <!--end content -->

Please answer before my face is rendered unrecognizable from untold faceplants to the keyboard. Thank you.

p.s. I have only added the AS to the button labeled “info”
