Forum:Can't get expandable and sortable table to work

I have a very long tabvel that I want to be able to collapseand also sort. I belive I have the correct syntax, but the collapsable option is not showing.

 * You are using the correct syntax, but your table does not collapse because you have not added the needed code to w:c:perpetuum:MediaWiki:Common.js. You need to follow the instructions here: w:c:dev:ShowHide --Gardimuer { ʈalk } 16:09, May 9, 2012 (UTC)
