hennzo Posted December 8, 2010 Share Posted December 8, 2010 Hi, I haven't taken a lot of time to go through your code, but first change this: $answer = $_POST['submit']; by: $answer = $_POST['answer']; Link to comment https://forums.phpfreaks.com/topic/220968-building-a-quiz-script-but-got-some-errors/#findComment-1144249 Share on other sites More sharing options...
