Customizing Wordpress Custom Categories

Hi, I have a directory builded on Wordpress. When someone submitting listing,he has to select location and category For example if he select Location: "Chicago" and Category: "Internet",the listing will be listed under 3 categories: [login to view URL] [login to view URL] [login to view URL] Now if add subcategory to locations or categories,the listing goes only under subcategory.. For example: If someone select category and subcategory : Internet>Hosting, the listing goes only under:"Hosting",but i want it to go also under "Internet" The same is with locations - i want the listings to be listed under both - main+ subcategory. The other thing i need is to have links on category [login to view URL] example: If one category has subcategories and there are lisitngs inside them,i need to have links to them on the main cateogry. In short, your job will be: [login to view URL] to go under main categories and subcategories (now they go only under subcategories) [login to view URL] links on category and location pages (to subcategories if they have listings) [login to view URL] breadcrumbs and links. [login to view URL] submit listings page subcategories to load on new drop-down field. I hate programmers to say:"You didn't said this or that" ,so i will tell you that way: THE PROJECT WILL BE DONE WHEN CATEGORIES ARE JUST LIKE I WANT THEM,NOTHING MORE,NOTHING [login to view URL] YOU DON'T LIKE MY TERMS -DO NOT BID.
