Admin Forum:Collapsible tables not collapsing

Hi, I've been updating the Spanish Silent Hill wiki, including adding collapsible templates to make navigation easier. I've already edited the MediaWiki:Wikia.css‎, MediaWiki:Monobook.css, MediaWiki:Common.css‎, and MediaWiki:Common.js‎‎ pages to match those of the English Silent Hill wiki (which I also admin on), but nothing is working. I don't know if there's some template in there that I'm missing (which wouldn't surprise me since the English wiki is fairly in-depth with its html and templates, whereas the original admin on the Spanish one never touched any templates at all) or what, but I'd love some help with this! :) 05:46, August 27, 2011 (UTC)
 * For example, you could contain the collapsible tables in a  element with class="collapsible." Then, you'll only need this JS:
