Hikashop as second level menu item

-- url of the page with the problem -- : www.acdnsw.org.au
-- HikaShop version -- : Starter 2.3.0
-- Joomla version -- : 2.5.17
-- PHP version -- : 5.3.27
-- Browser(s) name and version -- : Firefox
-- Error-message(debug-mod must be tuned on) -- : Error_message

I am completely new to Hikashop so this may be a very simplistic question. I just want to create a simple order form on a single page on my website. I want the order form to be accessed not from the top level of the main menu, but from the second level: e.g. if you look at my website, under Publications there is a menu item Order Form. I want to replace this using HikaShop. But when I created a publications listing menu item under Publications, HikaShop put two new menu items at the top level - a products listing and a categories listing. How can I achieve a HikaShop menu item at the second level?
Thanks.
