Are you referring to your JotForm titled "PeeWee Contact Form"? As I check your JotForm, the captcha field seems to be displaying properly.
If you are referring to something different, please let us know. We will be happy to assist you.
- yajohnson37068Answered on January 05, 2016 at 10:46 PMThat is the one I was referring to, but I decided to delete Captcha because
I found a post that said you have other ways of stopping spammers and only
offered Captcha because people requested it.
Is this the case? Or is Captcha really necessary to stop spammers from
hijacking a form?

A CAPTCHA (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart") is a type of challenge-response test used in computing to determine whether or not the user is human.
