try something like this..........

"<a href=" . append_sid('album_cat.' . PHP_EXT . '?cat_id=' . $cat_id . '&user_id=' . $userdata['user_id']) . ">LINK</a>"


in the lang_faq.php could look like..........

$faq[] = array("New Title", "<a href=" . append_sid('album_cat.' . PHP_EXT . '?cat_id=' . $cat_id . '&user_id=' . $userdata['user_id']) . ">LINK</a>");


.....of course $cat_id will need to be defined somewhere
