Board Thread:Support Requests - Designing Your Wiki/@comment-31795961-20171023021643/@comment-32354545-20171024025617

A template is some potentially dynamic content that is meant to be transcluded onto any number of pages. Every wiki has its own set of templates, though the templates from c:starter:Category:Templates are the most common, because they are the ones that exist by default on new wikis.

Your page c:awesome-comics-so-cool:Template:ComicNav seems to be copied from another wiki; in it is transcluded a  but it seems to expect a heavily modified version of Template:Navbox that is very modular, but the default version of the template is the one that exists on your wiki, and it is much more minimal, and will not recognize the same parameters.

You may copy the Template:Navbox from the same wiki as you copied ComicNav if you want. Or you can build a navbox from scratch, as I describe from my blog.
