Need help

[Richardtagger]

On a change password script i need it so that you enter your new password twice. If they aint equal then i want it rejected. i have

if((!$new2) = (!$new1)) {

$sql = mysql_query("SELECT * FROM users WHERE username='$username'");
$userid = mysql_result($sql,0,"userid");

mysql_query("UPDATE users SET password= '$new1' WHERE userid='$userid'");

include 'changepw.php';
}

whats wrong here? Thanx guys

if ($var1 != $var2)
  echo 'not equal';
