Sorry to say but we do not have features for "unique values" or for preventing duplicate values on a certain form field. But, we do have unique submissions feature where users can only submit 1 submissions per IP or per browser session. Here's a guide: http://www.jotform.com/help/64-What-does-Unique-Submission-Mean
Do let us know if you have further questions. Thanks!
