PsychoPy version (e.g. 1.84.x): 2020.2.8
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:

I’m trying to display a simple questionnaire using the form component.

What did you try to make it work?:

I created a basic working example with a single form component, and a CSV file with the required column headers.

This can be viewed at: James Lewis-Cheetham / questionnaire_example · GitLab (pavlovia.org)

What specifically went wrong when you tried that?:

The code immediately exits with the following error:

Experiment ended.

Thanks!

It might be because your csv file says the question is a radio but doesn’t give any reponses.

According to the docs the radio button will default to yes/no, and I still encounter the same error when changing the question to a different type. Thanks for taking a look though!
