Hi.
I'm search the manner of conditioning to field, for that when the user choice is "No", cannot sent the response. There is a select_one field in my survey, and the idea is that the user responds "yes" and can sent. If answer "no", that the button "Sent" don't active and cannot sent. The idea is this, but appear an error:

I don't find the sentence with "sent".
Do you have any experience with this?
Thank you very much!
Braulio.
