Re: header information problem

In the else part, you have the possibility to echo to the screen and 
later on, then header("Location: ...");

This is the bit which isn't allowed.

If you are doing header("Location: ...");, you are not allowed to echo 
before it.

do not match!<br />
   		Please try again!<br />";
   		include 'login_form.html';
