So I am trying to use XLQuiz to put quizzes on my site. It comes with an input field for someones name, but, because users are logged in on my site, their name is stored in a MySQL database. I want to eliminate the field and its processor and replace it with a "get from MySQL" function instead. the code is attached and embedded. This is only the file that contains the info about the field. I have the others and can end them if need be. All help is greatly appreciated.
