Hello,
If you have questions in French, please post in the French section of the forum.
That forum subject seems to be integration between HikaShop and the template and your last message seems to be related to taxes and zone configuration ; these are two subject very different and would be better in a different subject, which can ben find and help other users too (so does the thousand of existing messages).
Regards,
