Hello,
Please provide a lot more details about what you have done (general configuration, shipping settings, product settings) and your issue.
Best regards,
PS : And please do not duplicate your message between the "contact us" form and the forum ; it does not help to get faster answer but will have inevitably the total opposite effect because we will have more message to answer to !
