here, try this, do a search for "SELECT userid" tell you come to the second "SELECT userid" (it should get to the one that drops down)

replace SELECT userid down to AND userid <> with:

PHP Code:

SELECT userid
                    FROM user
                    WHERE username='".addslashes(htmlspecialchars($ausername))."'
                        AND userid <> $userid")) { 


plus, before replaceing, you should check to make sure the code is the same of above and if not, then replace it with that. hope this works
