second page:

$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
if(mysql_num_rows($result)) { // If the username and password are correct do the following;
$_SESSION['loggedin'] = 1; // Sets the session 'loggedin' to 1

if($check) {
// Check to see if the 'setcookie' box was ticked to remember the user
setcookie("Cookie[myusername]", $myusername, $time + 3600); // Sets the cookie username
setcookie("Cookie[mypassword]", $mypassword, $time + 3600); // Sets the cookie password
}

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");

header('Location: members/login_success.php'); // Forwards the user to this URL
exit();
}

else // If login is unsuccessful forwards the user back to the index page with an error
{
header('Location: error.php');
exit();
}
?>

the issue is, that the "remember me" feature does not actually remember the user when they check the box.  i can't figure out what i have wrong in my code.
