Problems with prices when linked to a group

Hi
I've products with different prices, they depend from member groups.
So, for example, group A pay 10€, and groups B pay 12€
Therefore, in "product management" (could it be more correct "productS management"?) > "Edit product with ID" > "Pricing settings" > "Add price" I addes a price and I selected:
1) "Store Configuration" AND "Price group" > the product is not visible in frontend for that group
2) ONLY "Price group" > the products is visible but price is 0
3) ONLY "Store Configuration" > the products is visible but price is not personalized
So, I wrong something? Or is there a problem in isotope?
Thanks

has somebody found the same problem? or it's only me?
thanks

I tried it on my isotope installation and it does work as expected. Which version are you using? I'm using an svn version of about a week ago (it could be a bug that is fixed)
