if I have a login form, and let's say someone submits the incorrect information, is ther anyway to let it try again on the same page, without giving me the header information error: Warning: Cannot modify header information - headers already sent by (output started at /home/serv04/www/chat/login.php:10) in /home/serv04/www/chat/login.php on line 55 ?? is there something I should do?
