Ok, I figured out the problem. On my article section which has categories (
http://www.pcshoptalk.com/content.php?2) this works. However, the Article section is a sub-section of the Home section and what's displayed on the main page is the Home section > Article sub section > categories > content.
So basically if I click on the "articles" link it will randomize the content shown on that page, but not on the front page. Can I somehow either display just the article section on the front page or make the article section not a sub section of home?
Does this make sense?
This is why I'm not a programmer ...
