Quizmaker - pop up prompt when trying to exit a quiz
I am working on a quiz and have set the restriction to only allow the users to leave the quiz once they have answered all of the questions. When the user tries to exit the quiz before answering all the questions, there is a pop up box that appears. At the moment, the text in the box is missing and just has "Ok". I would like to add some text, for example, "You must answer all questions before exiting the quiz". I have seen this before, but cannot now find the setting. Any suggestions please?
