Help a newbie please!

Alright, I finally got my own domain name (petewisdom.com) and I'm trying to move my fanlistings over to my site. I want to use PHPFanbase to manage my members but I am stuck on a part.

$dbhost = "??"; // usually this is localhost but if it doesn't work, check with your hosting provider

What exactly do they want? I'm using Cyberpixels and their TechSupport takes a day and a half to respond if not more.

Any help could be appreciated.

Edit:

Thank you so much! The 'localhost' what was the problem. Now the Tonks/Bill Fanlisting is a go.

I have a problem with the iframe horizontal scrollbar, but I can live with that.
