Jean "If I click on the 'Survey' (the Questionnaire activity) it responds as though it thinks I want to take the survey."
What do you mean? Do you mean that the only tab you can see is "View"? Please provide a screenshot. Did you create the questions in that questionnaire yourself? Can you create/modify questions in that questionnaire?
Was that questionnaire created as "public" in another course than the one you are viewing and by another teacher on your site? Can you switch from admin to teacher role and see what happens?
