Can't find the correct template to make final edit
 

I am at this step below in the template editing required to make this mod work however I can't find the code in the navbar template. Would it be somewhere else? My forum url is www.stepinthezone.com/forum

The problem is usually that you are trying to use a mod made for a different version of vbulletin. What works for me, is simply searching calendar.php as it is i believe all of the versions of vbulletin unless you deleted it. So, search calendar.php and a line somewhat similar to the one you need to search should show up. Simply put <td class="vbmenu_control"><a href="arcade.php?$session[sessionurl_q]">Arcade</a></td> right under that.

There was not even one entry for vbmenu_control in calendar.php. I don't know what to do, the arcade shows up in the admin cp, but where do I access it on my forums? I can't get it to show, nor can I make this final template error.

If you're using a skin other than the default, you'll have to search around.. it's most likely in 'header' as it was in mine (not under a category, just called header). From the looks of your skin there might be a template called "sidebar" or something along those lines.
