Trying to add a field to a .pdf report, but everytime I save it it disappears

I'm trying to add a field from a form into the .pdf that is sent to respondents, but everytime I add it in the pdf report it disappears. I've included a screenshot of the field I'm trying to add. It reads (with the code needed) as follows;

In consideration of {participantsFull27} (“Minor”) being permitted by UDC to participate in its activities and to use its equipment and facilities, I further agree to indemnify and hold harmless UDC from any and all claims which are brought by, or on behalf of Minor, and which are in any way connected with such use or participation by Minor.

Thanks,

-Warren

I've fixed it for you. This is because the Show Headers and Texts are unchecked in the form submissions page settings:
