hello i have two problems in prestashop i can't solve.
First i've set up my carriers correctly but in the checkout proccess no one of them appers and i get the error message ''invalid carrier or no carrier selected''.
Second i've added a color group for the customer to choose but again in the checkout proccess all colors appears under the product,not only the color that customer chose.

First problem solved(i was trying to ship to a country outside the us that's why shipping didn't work,because i haven't set up shipping outside us).
Any suggestions about the second?
