Newbie - Javascript Slideshow Help

Original slideshow
http://sandbox.scriptiny.com/javascript-slideshow/

I'm fairly new at creating slideshows and would really appreciate the help with a project that I'm working on. I'm attempting to create 3 rows of sliders that hold thumbnails directly beneath the large image. The original, of course, has just one row (I'd like each row to hold 4 images that are viewable and a total of around 12 to 15 images...obviously some hidden). Please keep in mind I'm new at this. I've been playing with this script for hours and nothing seems to be working. The html if viewable from the link above. I've copied the css below. Please let me know if there is anything else that you need. Thanks again. I really really appreciate it!
