Auto Drop Down feature implementation

Have a look at the attached table structure above. Basically, we have 3 tables that are inter-related. We have an ASP file which lets us choose the category, subcategory and size using drop down. HOwever, what we would like you to do is change it so that as soon as we select the category, it populates the subcategories using javascript. Right now, it lists all the subcategories and very often we select a subcategory belonging to another category. After the subcategories are narrowed down, we then want the size drop down menu to be filled with the sizes that go with the subcategories(notice they are seprated by commas) Easy money if you have done it before. We have two pages that need to be changed...but should nto require more than copy paste i think. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
