I looked at your article that did not cover how to highlight the tab.
See the issue is I am wrapping the vb header and footer around a totally separate application in another directory outside vb. Basically I use a little file I include in vb which loads the autoloader config and the templater calls to call the header footer and define the vaiables $header and $footer. I then basically include that file and my custom page outside of vb is wrapped with the vb header footer.

That should give you a hint of what I have done. I think Internet Brands things that everybody can do things with a little widget vb5 is kind of funny in a way like that. I looked at there widget thing that was hilarious.
