Error establishing a database connection

Please can anyone help me?

I am trying to set it up wordpress urgently but its not working.

The information I have is on my server is Nickname, URL, password, Server (which is the domain name plus co.uk – is this an unusual format?) & username (a number preceeded by the letter u – is this an unusual format?). Where would these fit within the below?

// ** MySQL settings – You can get this info from your web host ** //
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘putyourdbnamehere’);

/** MySQL database username */
define(‘DB_USER’, ‘usernamehere’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘yourpasswordhere’);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);
