don't know what's wrong

Does anybody know why this script gives this error?
Fatal error: Call to a member function query() on a non-object in C:\xampp\htdocs\pokerday\jet_30\html\login0.php on line 18

The form is situated in login.php and the code below is login0.php

<?php

if (isset($_POST['submit'])) { // if form has been submitted

    /* check they filled in what they were supposed to and authenticate */
    if(!$_POST['uname'] | !$_POST['passwd']) {
        die('You did not fill in a required field.');
    }

    // authenticate.

    if (!get_magic_quotes_gpc()) {
        $_POST['uname'] = addslashes($_POST['uname']);
    }
	
    $qry = "SELECT username, password FROM users WHERE username = '".$_POST['uname']."'";
    $check = $db_object->query($qry);          /// this is line 18

    if (DB::isError($check) || $check->numRows() == 0) {
        die('That username does not exist in our database.');
    }

    $info = $check->fetchRow();

    // check passwords match

    $_POST['passwd'] = stripslashes($_POST['passwd']);
    $info['password'] = stripslashes($info['password']);
    $_POST['passwd'] = md5($_POST['passwd']);

    if ($_POST['passwd'] != $info['password']) {
        die('Incorrect password, please try again.');
    }

    // if we get here username and password are correct, 
    //register session variables and set last login time.

    $date = date('m d, Y');

    $qry = "UPDATE users SET last_login = '$date' WHERE username = '".$_POST['uname']."'";
    $update_login = $db_object->query($qry);

    $_POST['uname'] = stripslashes($_POST['uname']);
    $_SESSION['username'] = $_POST['uname'];
    $_SESSION['password'] = $_POST['passwd'];
    $db_object->disconnect();
?>

<h1>Logged in</h1>
<p>Welcome back <?php echo $_SESSION['username']; ?>, you are logged in.</p>

<?php

} else {    // if form hasn't been submitted

?>
ga naar member.php
<?php
}
?>

problem resolved, thanks to the help of my brother who just came home

looks like the connection to the DB failed as $db_object was not a valid connection resource.
