got the first page working fine - having a little more 'fun' trying to prevent other pages from being visible without login.
first page - index.php works logs in, creates session id and shows restricted content on the page.
there's a url on index.php to a page called batchlist.php.
and in batchlist.php i've added the line as per the article
but i get the messagePHP Code:
$uid = $u->requireAuthentication("displayLogin");
any thoughts ?
