I am confused because I see a footnav.php and inside that I see it referencing a position 'footnav'. If I try to assign a menu to the position 'footnav' it is not there. I looked in the templateDetails.xml and noticed the position wasn't there. When I add it I then see the position option for the menu to be assigned to. I assign it to the position 'footnav' but the menu doesn't show up on the frontend in the footer. What am I doing wrong? It seems logical that you would assign 'footnav' to a menu that is meant to be the footer navigation.
