Just getting started-

I am just getting started and trying to figure out how to get the information from my database. I am trying to install WordPress on my computer so I am using localhost, WAMPServer 2.1. According to what I have read, I just need to make sure my wp-config.php file matches what I input into the initial wordpress prompt. The following information is requested:

Database name: wordpress
Database username: root
Database password: “left blank”
Database Host: localhost
Table prefix: wp_

I have even gone to the WordPress web site and copied the following keys:

define(‘AUTH_KEY’,
define(‘SECURE_AUTH_KEY’,
define(‘LOGGED_IN_KEY’,
define(‘NONCE_KEY’,
define(‘AUTH_SALT’,
define(‘SECURE_AUTH_SALT’,
define(‘LOGGED_IN_SALT’,
define(‘NONCE_SALT’,

But I still get:

Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the wordpress database.

Are you sure it exists?
Does the user root have permission to use the wordpress database?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?

What am I doing wrong.

Thanks
