Why I cannot add a form to Facebook page?

não consegui instalar o formulário na minha fan page , o face book não aceitou alguém pode me ajudar ??

Facebook requires pages to have more than 2000 followers to add tabs, tabs are required to add your form to your Facebook page. 

This is not a limit imposed by JotForm, it's on the Facebook side instead, here's a link with more information about it: https://developers.facebook.com/docs/pages/tabs/ 

Make sure you have more than 2000 followers on your page, if you keep experiencing the error, let us know.
