I was the original user that requested and paid for the modification of the link under help. I wanted a static page that I can put under 'Help' but not show up. Hence they added that 'Show Link' check box. To add your 'Ordering Policy' all you have to do is create the static page. You don't need to change any code. Here is a link to my site
www.vegi.ws/cart/home.php. I have renamed 'Help' to 'Information' I have any static pages that are not shown under 'help/information'. Click 'Show Dates' you will see all my current Art & Craft events I attend. With this page, you can see links to my prior years attendances. Those prior years static page are NOT shown under 'help/information. Hope this help you in creating your 'Ordering Policy' page under 'Help' tab.
BTW, if this gets you to what you want, you probably want to remove all that you have modified. If I can be of further, please post response.
