Afraid your screen images didnt link properly so I cannot see them.
Assuming your wamp icon is green, I preume that you have edited the testmysql.php incorrectly.
If you have not changed the mysql 'root' user in any way i.e. added a password your code should look like this:
$link = mysql_connect('localhost','root','');
if (!$link) {
die('Could not connect to MySQL: ' . mysql_error());
