Flash 8 & XML Photo Gallery Tutorial

I am attempting the Kirupa XML and Flash Photogallery tutorial in Flash 8. Whenever I do the Publish Preview my captions simply say “Undefined” and the animation doesn’t work. It seems the XML file isn’t being recognized. All files are saved in the same folder and all code appears to match up. I am assuming this is due to my using Flash 8. How can I fix this? (I am using actionscript 2.0)
