(I guess caching parameterless templates is a smart thing to do... it just doesn't agree with global variables.) |

This template requires a small workaround to avoid the MediaWiki parser caching the template and not persisting the variable properly. It must be called with an empty argument (or any sort of argument), like so: <code><nowiki>{{Evenodd|}}</nowiki></code> - note the pipe. This is placed wherever an "odd" or "even" value is needed that's the opposite of the previous instance of this template on the same page. | This template requires a small workaround to avoid the MediaWiki parser caching the template and not persisting the variable properly.
