XML thumbnail gallery in an external SWF

programming flash
1

Hi guys, sorry to start another thread concerning the XML thumbnail gallery (I know there’s a bizzilion of them!) but my question is simple enough:

I have built my thumbnail gallery in an eternal movie, which will be loaded into my main flash movie. However, the left and right scroller does not work when I preview the gallery page into my main flash movie. I have to alter the script, but not sure how.

I’m stumped. Can anyone help?
Here is the code.

function loadXML(loaded) {
 if (loaded) {
  xmlNode = this.firstChild;
  image = [];
  description = [];
  thumbnails = [];
  total = xmlNode.childNodes.length;
  for (i=0; i<total; i++) {
   image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
   description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
   thumbnails* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
   thumbnails_fn(i);
  }
  firstImage();
 } else {
  content = "file not loaded!";
 }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
