Flash/xml slide show

i started with the tutorial slide show found here, but after altering its appearance, and adding a center item on the mc that contains the image (loaded) the image does not seem to load on all browsers. it is successfull on mac firefox/safari… not ie. and not pc friendly at all.

any suggestions?
**
as code:**

function loadXML(loaded) {

if (loaded) {

xmlNode = this.firstChild;
image = [];
description = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {

image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;

}
firstImage();

} else {

content = “file failed - check xml”;

}

}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(‘load.xml’);

Key.addListener(listen);

p = 0;
this.onEnterFrame = function() {

loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {

preloader.preload_bar._xscale = 100*loaded/filesize;

} else {

preloader._visible = false;
if (picture._alpha<100) {

picture._alpha += 10;

}

}

};
function nextImage() {

if (p<(total-1)) {

p++;
if (loaded == filesize) {

picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
picture_num();

}

}

}

function prevImage() {

if (p>0) {

p–;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
picture_num();

}

}
function firstImage() {

picture._alpha = 0;
picture.loadMovie(image[0], 1);
desc_txt.text = description[0];
picture_num();

}

}
function picture_num() {

}

picture mc center code:

**onClipEvent(enterFrame){
stage_width = 256;
stage_height = 256;
if(this.getBytesLoaded() >= this.getBytesTotal() && this.getBytesTotal() >500){
centerw = stage_width/2;
centerh = stage_height/2;
this._x = centerw-(this._width/2);
this._y = centerh-(this._height/2);
}
