problem with admin.php

hello,

i had create a new table in sql database with the install.php, then i opened the admin.php and it displayed the following site:

Warning: Access denied for user: 'root@localhost' (Using password: NO) in /home/virtual_users/jaha.dk/limpbizkit/guestbook/lib/mysql.class.php on line 30

Warning: MySQL Connection Failed: Access denied for user: 'root@localhost' (Using password: NO) in /home/virtual_users/jaha.dk/limpbizkit/guestbook/lib/mysql.class.php on line 30

what does that mean?

I'm just guessing, but it looks like you didn't set up your user name and password for your database in your variables.
