error when scrolling to page 2 on form

I have a pdf file I created a dynamic form from. It is on pages 2-5.

On form ready, I set the pages to "hidden". That works fine.

on my first page I have a check box. When I click the checkbox and then scroll down to see the other pages, I am getting following error. I cannot see the problem anywhere. Can anyone explain what Regions mean. I figure I am missing something on a define. thank you very much
