Flash 8 UI Tree Help!

programming flash

Hello, basically let me explain what the heck i want it to do. I NEED a tree navigation on the left side of the screen, and when i select a heading on the tree i need it to load a corosponding SWF into a movieclip holder on the right side of the screen. Not only that, but i need the menu item on the tree to stay highlighted (as to show where you are) i have been trying to do this for 2 days using the component and every other method i can imagine…the nearest i got was managing to get an swf on a specific level (such as 2) but pointing it to a mc_holder proves futile, and i dont even know how to go about keeping the tree menu item highlighted…

I manage to get flash to pull up a swf using the following code, its crude, but it works. unfortunatly it loads it to 0,0 and simply will not load to anything except a layer
eg.

if (url) {
loadMovie(url, "mc_holder");

produces the swf being loaded in a new IE window.

Im referencing this XML code

<node>
<node label="Test">
<node label="Test SWF load" url="HomeTube.swf" />
</node>
</node>

And this is my .as file for the Tree

import mx.controls.Tree;
class TreeNavMenu extends MovieClip {
 var menuXML:XML;
 var menuTree:Tree;
 function TreeNavMenu() {
  // Set up the appearance of the tree and event handlers
  menuTree.setStyle("fontFamily", "_sans");
  menuTree.setStyle("fontSize", 12);
  // Load the menu XML
  var treeNavMenu = this;
  menuXML = new XML();
  menuXML.ignoreWhite = true;
  menuXML.load("TreeNavMenu.xml");
  menuXML.onLoad = function() {
   treeNavMenu.onMenuLoaded();
  };
 }
 function change(event:Object) {
  if (menuTree == event.target) {
   var node = menuTree.selectedItem;
   // If this is a branch, expand/collapse it
   if (menuTree.getIsBranch(node)) {
    menuTree.setIsOpen(node, !menuTree.getIsOpen(node), true);
   }
   // If this is a hyperlink, jump to it 
   var url = node.attributes.url;
   if (url) {
    loadMovienum(url, "mc");
   }
   // Clear any selection 
   menuTree.selectedNode = null;
  }
 }
 function onMenuLoaded() {
  menuTree.dataProvider = menuXML.firstChild;
  menuTree.addEventListener("change", this);
 }
}

hmm…anyone have any ideas. i mean…i hope to have 30+ menu items all which call a different SWF to the holder. and then after that, figure out how to make the menu item stay highlighted until you select another item.

cheers.
