[RESOLVED] I don't get it - SQL? Whats up with this

[samtheman]

<?
//Database Information

$dbhost = "";
$dbname = "";
$dbuser = "";
$dbpass = "";
//Connect to database

mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());

session_start();
$username = $_POST[‘username’];
$password = md5($_POST[‘password’]);

$query = (“SELECT * from users where username=’$username’ and password=’$password’”); - THIS IS THE Erroneous Line 

$result = mysql_query($query);

if (mysql_num_rows($result) != 1) {
$error = “Bad Login”;
    include “index.htm”;

} else {
    $_SESSION[‘username’] = “$username”;
    include “X.php”;
}

?>

Error: Unexpected T_STRING on Line 17 ( See above) I've marked it.
