Error when submitting Quick Add from requester login

Made some additions to the Quick Add form and when a requester tries to submit, it gets an error and says to contact the administrator.

I am new to this type of software. We are going to be using this as a support system at a high school. We have two IT guys, including me, and about 400 students. Students are "requesters" through google apps EDU.

I wouldn't even mind turning quick add off altogether but I can't figure that out either.
