ActionScript 2.0 :: XML-based Slideshow?

I'm building a portfolio website for my wife and I. I've basically taken Kirupa's tutorial (XML photo gallery) and have tried to use it. I have several sections, or galleries, that I would like to show after clicking the "portfolio" button. But the problem right now is that only the first image from each gallery gets loaded into the main viewing area, even though the thumbnails themselves seem to work fine. Here is our site as it stands now.

The thing is, the site works locally on my computer, but once I upload it to the server, it doesn't work.I have removed some of the extraneous code from the original tutorial which I wasn't using, mainly so that it would be easier for me to read and work with. And I've checked and double checked to make sure I didn't delete something necessary. As I said, the site works locally on my computer.

I thought the problem had to do with relative or absolute paths, but that doesn't seem to be the case. I think what's happening is that the arrays for each of the galleries, for some reason beyond my understanding, are not being set-up correctly. The first image for each gallery shows up fine, but subsequent images do not.In my main movie, I placed an empty movieclip called "myHolder" on the stage. When a user clicks one of the sections "advertising," "design," etc. under the main "portfolio" button, one of the five gallery movieclips from the library is attached to the myHolder movieclip. Inside each of those library movieclips is the slideshow set-up with the code as I've altered it. Within the code is an xmlData.load("Some.xml") pointer that points to one of five different xml files that contain the appropriate linkage for each gallery.
