Hi sassypie. Welcome to the forums.
Those two pages are nothing alike—the one with the slider built with divs and the other (where the slider is missing) on tables.
The one that's not working seems to lack the jQuery script that makes it work, but that script also references a div called "myGallery" that doesn't exist on the table page either.
What code do you see on the table-based page? You need to have the picture files, div containers and so in on the page for the script to be able to act on them.
