I am trying to change the layout of the product catalogue page. Below is a link to the page I am referring too.
http://scamps.co.nz/zencart/index.ph...=index&cPath=1

What I would like to do is have the catalogues displayed as 3 columns and in rows so there isn't so much scrolling going on.

What page do I need to edit to achieve this and what code do I need to change?
