There seems to be a problem with advancing levels in the JavaScript Security Game.
This will be fixed as soon as possible.
In the meantime, just read the JavaScript for each level, type in the password, and if it says "Password Correct" and doesn't go to the next level, just type in the password followed by .php or whatever it says.
Example:
http :// darkaq.byethost3.com/javascript/ THEPASSWORD.php
*replace THEPASSWORD with the password from the script.
*Also, take out the spaces.
