I want to make attachments a required field for the user, but there is no sort of validation for the Attachment control.
I tried using the solution in this (http://www.vadimtabakman.com/nintex-forms-attachment-required.aspx) but even in the test form, after attaching something, the Nintex form does not accept the attachment.
How do I attach a file and make sure it goes through? And how do I make the attachments a required field?
Is there a possible rule or any other possible solution to solve this?
