Thanks for your help

Installing PHP on your server is not enough, your web server software has to be setup to support it as well. Has it been?

If the URL you gave is correct absolutley nothing comes up...

The first step would be to check the permissions for the file...

I haven't done any unix (assuming it is)...

the file permissions for the folder (html) should be 755.
-- chmod 755 html

the permissions for the files in the directory should be 644

-- chmod 644 *.html

What do your error logs say?

I'd have to agree with making sure that php is set up properly first. I get some pretty funky errors when going there, after you set up php, maybe you could re-upload the script. It doesn't look like your webserver is serving up any php at all.
