As soon as I add the code to the header page with the if and else if. Nothing loads on the page.

To be a bit more specific...

If you go to http://secure.brius.com/knowledgebase.php

Can you see the greyish bar that has Overview....etc, FAQ.

Those image links are included in the header of this script and I need to add a <strong> tag to the FAQ link when the user is on that page.

When they go to the order page, I then need to add a <strong> tag to the Order link and remove the tag from the FAQ.

Make a bit more sense lol
