javascript 3 row tabs in php page using css/ul

We have a landing page written in php, which is auto-populated based on a mysql query with information in 15 tabs in 2 rows. We need help with the tabs, specifically to display with the correct spacing and background images, which I have generated a left, middle spacer and right image for both active and inactive tabs. The tabs are simply (right now) a big ul with a class, and the class is calling a javascript file that references a css file that are both well commented. We can't get the spacing right, and don't have the time to deal with it.
