[PHP] login

I have this problem:


Notice: Use of undefined constant password - assumed 'password' in C:\wamp\www\Projects\Css_hjemmeside\login.php on line 5


--login.php--
<?php
$username = $_POST['username'];
$password = $_POST['password'];

if($username&&password) {
$connect = mysql_connect("localhost","root","") or die("Mysql error");
mysql_select_db("css_site") or die("Mysql error");
}
else
die("Type a uername and password to login.");

?>

PHP Code:

---

<?php
$username = $_POST['username'];
$password = $_POST['password'];

if($username && $password) { //you had "$username&&password"
$connect = mysql_connect("localhost","root","") or die("Mysql error");
mysql_select_db("css_site") or die("Mysql error");
}
else {
die("Type a uername and password to login.");
}
?>

Thanks you
