"Undefined variable $success" if mailchimp isnt defined.

[ccbeyer]

Currently, I have the mailchimp toggle disabled. The code in Formerly_SubmissionsService.php line 40 says if ($form->mailchimp && isset($submission->{$emailHandle})) { and in that if block, $success is set to either true or false. Then, outside of that if block (line 67), $success is returned. In my case, since mailchip isnt enable, i believe thats causing $form->mailchimp to return false, and therefore $success is not being set and is null, which is making Craft CMS throw the error "Undefined variable $success". Why is success being returned if its not always defined?

To add more detail, i dont currently have any formerly settings in the craft/config/general.php file, but that shouldn't effect this right?

Having this issue as well. Hacked myself a solution by moving $success = true; to outside if ($form->mailchimp && isset($submission->{$emailHandle})) {...}

Thanks @zacharybrady, that just helped me out as well.
