Enabling Mandatory Text Entry in a Textbox


In my experiment (script attached), I am asking participants to either answer questions or type responses before moving on to the next trial. Currently, participants are not ‘forced’ to type in any responses and can still proceed to the next trial by pressing the Enter key. However, I would like to ensure that a response must be typed before they can advance to the next trial.

How can I implement this change in the builder? Any assistance would be greatly appreciated.

Hi, I’ve created a minimal demo here where a clickable Next button only appears after something has been typed in the textbox. Hope this helps :slight_smile:

Thank you very much for your help.
