Hi
Gloria,
Thank you for using Cvent Community!
I checked your account and noticed that you have created a Contact Custom Field - please select all that apply, to be made visible when someone selects Yes for the "Do you have any dietary restrictions?" Contact Custom Field.
When you run the Product Ad Hoc report, you should also move the Contact Custom Field 'please select all that apply' from Available to Selected side and then run the report to see what the invitees selected.
Hope this helps!
Regards,
