Setting up mySQL & php configure

Hi,
I've just set up a mySQL database for an ecommerce site. I've got the username password bit in the configure.php but I'm stuck on the path for it. The instructions include a reference to path names:- "define('DIR_FS_CATALOG', '/home/username/public_html/)'" but dreamhost doesn't use the same path structure. Could someone point me in the right direction please? Do I need to have the DH server name and my username and/or domain in there?
I haven't found any references in the forum search or the wiki pages.

Cheers.

I think you would just change /home/username/public_html to /home/username/domainname. If you have set a different path when registering the domain then you would need to make it that path instead.
