Category problem

Hello,
Each category at Every Buck Counts page, namely:- Loans, Card, Banking, Make Money and Save Money has got 3 subcategories in the form of columns i.e. Intro, Services and Read and Learn.
I wanted to bring to your attention that the subcategory page is only taking 12 entries in one row and if I am trying to add the next entry, it is adding another row in the form of the extended new menu below.
Please help me out with this.

The page I need help with: [log in to see the link]
