Demographic form at the beginning of online experiments

About the demographic form at the beginning of online experiments where you can ask whatever information from the participant, it says by default that “Fields marked with an asterisk (*) are required” BUT I don’t know how to actually make them mandatory/or put an asterisk on them. Is there such an option? cause currently participant can just click OK (and start the experiment) without filling in the questions.

URL of experiment:

Description of the problem:

Hi @Laura_Pissani, to make required fields, add an asterisk (*) to the entry in the Experiment Settings dialog e.g.,


Now the participant field will need an entry before the participant can continue.
