Modifications CRE Loaded Multi Store

I have installed Multi Store for my website with default store and 1 child store. Now I installed a new template for a new child2 store. I have some small problems with the new child2 store. It is not acting like the child1 store and the default store. Something with the new template files? This is the list: * ( General problem)Adding new products in the admin, the price from the product is not saved in the database * New template - Specials on main page are not only the specials for this template but showing all specials from all templates * New template - Is not showing the right categories for this templates but showing all categories I want to know how you did the work so I learn for the next template! What files did you modify and how?
