The script does not compile with a recent (2.14) version of Template::Toolkit. It can also not be tested online (tpol.daemon.de/quizz/ (tpol.daemon.de/quizz/)) because Template::Toolkit is not installed there.
I lost all ambition to do further testing when I saw that the script used the option "fatalsToBrowser" of CGI::Carp and the docs didn't even mention that this has to be removed in a production environment.
