The once-per-session Submissions button in the Form Properties dialog is not recommended for Polls. This button makes the Poll Web page unviewable to users who try to resubmit the form.

The author adds the conditional tag to the body of a Web page. Users who try to submit a Poll more than once will see the alternate content.
