XML and Flash Photo Gallery

I was using the instructions given on the Kirupa.com website for the XML/Flash Photo Gallery and have run into a slight problem. I can get my photos to show up and can also have the buttons work to scroll the pictures both previous and next. My only problem is that I cannot get the description of the picture to show nor the picture count. I have taken the action script and xml file directly from the website and cannot understand why it won’t work. Can someone please offer me some kind of idea as to what the problem may be or if there is an alternative way to get this done using XML?
