Header Stylesheet?
 

I have posted this in vBulletin.org but nobody has provided with me with a response.

Basically I am adding a navigation bar in my forums header template bit, it also uses a custom style sheet which I have declared in the header. It has css effects too so I can see that it works, the issue I am having though, is the font I want from the stylesheet isn't working and it looks like its using the default font stated in the main css of the template.

Is there a way to fix it?
