Registrants can't move forward to the next screen
If you are finding your registrants are not able to move forward to the payment page, it could be due to a small check box:
Your special comments box is an opportunity for you to instruct your golfers or to require the user to enter text before proceeding (another way to collect some information). Checking off this box means that text MUST be entered into the field.
Double check that this has not been checked off. Even if the special comments box is left blank, it will still require the user enters text before proceeding.
