Mysql & other databases - Database not connecting - Wamp Server

Hi

I got to develop my whole database in Wampserver 2.1 (it's the latest set). But now I cannot connect to MySQL through PHP in Wamp. I have searched a lot but still have no clue as to what is causing problems.

No errors are being displayed. I have tried a number of code combination including "if(!)" and nothing has worked.

CAN ANYONE HELP PLEASE.

Here is the current code I am trying which returns blank page:

<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'xyz';
$db = 'scorecard';

$conn = mysql_connect($dbhost,$dbuser,$dbpass);
if (!$conn)
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
?>

<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'xyz';
$db = 'scorecard';

$conn = mysql_connect($dbhost,$dbuser,$dbpass);
if (!$conn)
{
die('Could not connect: ' . mysql_error());
}
else
{
echo 'Connected successfully';
}
?>
