How to edit links in custom theme header

[spin6]

I cant figure out how to change the menu link references along the header of my prestashop pages. I have a custom theme so i believe this change needs to be done in the code. I've successfully made these changes to my non-prestashop pages which are in HTML (like my home page www.hvtvmounts.com) but cant figure out how to do the same on the prestashop pages (like www.hvtvmounts.com/shop).

 

What i want to change is lines 62-73 shown below. Can someone tell me how to make changes to this?

 

<ul class="topmenu">
