Multistore not adding price to cart

Hi all,
just trying to use multistore, i've added a product to the store and when i click add to cart is says 1 item and adds the item but the price stays at £0.00?

I also added options to the product with an extra £1.00 for certain colours and sizes and they add fine just not the base product price?

also it onlys happens on the base layer product in the accessories range?
Any Ideas?
