Registration Form resets in Browser rather than showing "Thank You" Page
After filling out my "Registration Form" in browser, and clicking Submit, the form "resets" and includes most of my information, but I have to re-enter passwords, and Captcha and challenge question.
This continues (looks like form moves a little each time, and never reveals the "Thank You for Registering" page. And of course, database is not accessed.
Below is the link to the page.
Any help will be very much appreciated!
