Test results only ever shows 0%

Hi there,I have just made my first quiz. All was going smoothly until I discovered that the test results page only ever shows 0% even when I get all questions right. I feel I am missing something simple but I just can't work it out.Here is how the quiz is set up:On the course content page the user clicks a button to go to the Test. I have organised the test so it has an introduction page, and then 8 questions, each on a new page that I have added manually. Then there is the Last Test Page with a "You finished" type message, and the Done/Submit button. It all works fine up to there. But once I click Done, my Custom Test Results Page displays fine, except it shows that every question is unanswered and my score is 0% FAILED!Also, sometimes when the test results page displays, there are huge white spaces between each of the Question Results Groups.Any ideas what I'm doing wrong? It's obviously not registering the selections I am making when I take the quiz.I have it set to ensure all questions are answered, and the Results tab of the Test properties box is ticked for "Show test results to student after end of test", "Grade the test", and "Customized test results".The Lowest passing score is set at 80.
