Arcade Script - Make Level three catagories possible

PROJECT #1 I own [login to view URL] and i use the script found here http://www.phparcadescript.com. The problem with it is it only lets me enter 2 levels of catagorys. Example: I can only enter CARTOONS then in the catagory I can put like FAMILY GUY but that is it. CARTOONS -> FAMILY GUY What i need to do is add a 3rd level of category's CARTOONS -> FAMILY GUY -> SEASON 1 This should be an easy project so i am only willing to pay 30-50 Thanks Ben !PS! you will have to upload the script to your server and then write instructions for me on how to do it to my site. you will not be given access to my site.
