I've got a 4 item horizontal scrollable section on my page, with 4 image (as buttons) in each panel that I want to use as navigation. I have been able to use the class="next" and class="previous" tools so the buttons perform those functions, moving 1 panel up or down. But what I really need it to do is to go to a specific panel. The first button should go to the first panel, and the 4th to the last panel, etc.

I just started using this tool about a week ago so I'm a bit new on this, but any help/suggestions you can give is very much appreciated.
