First, make sure your answers for each question show up on the screen. If you were required to click on a small circle, make sure there is a dot in each circle that requires a response. Sometimes, when you click quickly on the circle the dot may appear, but it does not stay when you move to the next question.
You may also try taking the survey from a different browser.
If you continue to have difficulty, please email us at firstname.lastname@example.org.
