The code used on Goosebumps Wiki has really nothing to do with Help:Tabber. Instead, that wiki is using Template:Tabber/Book, Template:TabberSelect, Template:TabberNoSelect, and Template:Spacing and probably some CSS to create their page tabbers. If you want to recreate that, you would need to copy at least the first three templates over (with credit to that wiki!), and use it exactly the same way as on that wiki.
