Avance Guestbook - Mysql

I'm trying to create the guestbook db and tables from
http://www.yourDomain.com/guestbook/install.php
but I get Error message:

Unable to select database: phpBook
Error Number: 1044 Access denied for user: 'jack' to database 'phpBook'

please let me know what's the problem.

thanks,
jack

make sure /admin/config.inc

is set properly i.e

db, host, user, pass

it seems everything properly configured!!
should I do anything with mysql server??
mysql is on different server and I use the
IP address.

thanks for your prompt reply.

Don't forget to specify the port where your mysql server is running on

e.g.

$GB_DB["host"] = "134.234.12.89:3306";
