User Submitted Data

Sorry, I know this question has been asked before but cannot locate an answer to help me.

I do not have the "User Submitted Data" checkbox to enable me to attach the information rendered on my form in the e-mail I send to the users.

My form is open for support. Please review it and tell me what I need to do.

Note: I had it in the very beginning when I was testing the firm, but it is missing now.

Thank you,
Vanessa
