Form Won't Send Checkbox is Unchecked
I have a form with a check box for each golf course. When all of the boxes are checked the form submits. But when one or more of the boxes is unchecked then the form won't submit. The fields aren't required, so I don't know why they won't work. The site is golf_courses_PlayedBeforeMembership.php and I've attached the php doc below. Thanks for the help.
