Price not changing

Price not changing

Hi,
I`m new here and first of all i want to tell you that this is the best shopping component ever, but i have 2 problems.
1. I add a product and i set 3 attribute prices. When i change the atribute form (ex Small - Large) the price don`t change. I see the price only if i add to cart.

2. There is a sef plugin for SH404Sef? because the sef url are very important for optimisation.

Best regards.
Alin

Aw: Price not changing

1. set tab info - price + tab attribute
2. use alias in joomshopping (category/product.html)
