Hi,
1. Can you show me through some screenshots how did you configured your content menu which have the ID number 206 through "Hikashop->Display->Content menus" ?
2.
While I am changing this code let me know how to get the joomla user group in your programs as I will also need to hide price and add to cart from anyone who is not in group author.
The solution will probably be to use
Access levels through the "Access level" tab of your product page, so you'll be able to restrict the access to your products.
Note that ACL are available through the
business version of Hikashop.
