This message means that something was sent before line 12. In
your case, the HTML. All things that have to do with headers must be
before ANYTHING is sent to the browser. If you need to have the HTML
before a setcookie(), header(), or another header-based PHP action,
check into ob_start() and the other output-buffering functions PHP has
available.
