MySQL error

[John]

I new to PHP, MySQL and Apache. I installed XAMPP today( I am running Windows XP) and everything seems to be working so far with one exception. When I click on CD collection I get the following:

Warning: mysql_connect() [function.mysql-connect]: Access denied for
user 'root'@'localhost' (using password: NO) in C:\apachefriends\xampp\htdocs\xampp\cds.php on line 65

Could not connect to database!
Is MySQL running or did you change the password?

What does this mean?

Thanks

You have changed the password for the MySQL user "root"...
(XAMPP security?)
