I have a tracker with just a few fields: user (auto assigned by creator), the quiz question (text area type), and points earned (numeric field).
Properties/permissions set per the tracker are: creator can view items and insert items, but should not be able to edit items (that is, he is only allowed one submission).
I have one item per user selected, modify items deselected, the quiz question set to immutable after creation, I've set the tracker permissions to include insert and view by 'student', but edit limited to group 'instructors' and obviously, admin.
I have tried every combination of permissions (by field, tracker, and object permissions) but when I log in as a 'student' I can reload the "Quizzes" wiki page and modify my entry for the text box and submit button will show up. Ideally, once the quiz is submitted, the error message of "You've already taken this quiz" (which should be available in the field properties, if I'm correct), should appear and the trackerlist should show the submitted answer and a blank space for point earned (since it has not been graded yet).
I do not want to use the Quiz feature for it doesn't include short answer.
Thanks for your help and let me know if I can clarify what I'm trying to accomplish.
