Let me second benGallery and also say you need a good grip on the php language so as to do common task like mysql database or any other database for that matter. In anycase here is a much more simpler connection script

<?php
$hostname = "localhost";
$database = "yourdatabasename";
$username = "root";
$password = "yourpassword";
$conn = mysql_pconnect($hostname, $username, $password) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db('yourdatabasename');
?>

just paste this at the start of the source code page and be sure to substistute "yourdatabasename" and "yourpassword" with their actual values
