Redirection won't work

[odetron]

ok so i ave this code

session_start();


$username = $_POST[‘username’];
$password = md5($_POST[‘password’]);
$logingood = 1;
$query = "SELECT * FROM users WHERE username = '" . $username . "' AND password = '" . $password . "'";

$result = mysql_query($query);
if (mysql_num_rows($result) != 1) {
$error = 'Bad Login';
    include (“login.html”);
} else {
    $_SESSION[‘username’] = '$username';
    $logingood = 2;
}
if ($logingood == 2)
{
echo "Welcome! I will now redirect you to your control Panel!";
if ($username == Odetron)
{
header("location: http://odetron.freehostia.com/Test/comics/comics/admin/");

}
else
{
echo "You are not an admin so get out ";
}
}
?>

I am mainly looking at the section

if ($username == Odetron)
{
header("location: http://odetron.freehostia.com/Test/comics/comics/admin/");

}
else
{
echo "You are not an admin so get out ";
}
}

What its supposed to do is make the user be redirected to the admin cp if there username is odetron, but even thought the username is odetron its saying you are not an admin. what was my error?
