oscommerce category module changes

Ok here is what I need done the oscommerce site is running on oscommerce using the sts template system [login to view URL] This is the sts template [login to view URL] I have created a sts command called $categorybox2 and its linked to php categories file called /includes/boxes/[login to view URL] currently this module is displaying all subcategories in the store and I'm hiding the too level output via css I want it to display only the subcategory items in the current category there in. These are all the top level categories and they are listed in the top menu. # Lingerie # Panties # Plus Sizes # Shoes # Swimwear # Bridal # Clothing # Costumes # Dresses when in any one of these top level categories the left menu should only display the subcategories of those top level categories and by default when on the home page or checkout pages it should show only the subcategories from the first top level category which is currently Lingerie. So you will be working on one file [login to view URL], you are not permitted to change any other files nor will it be required to change any other files. So dont do it, this is a highly stable super modded out oscommerce system. I need someone to start right away on this and finish within 4 hours so I can continue my work on it.
