Error when running a Form

Hello! I would appreciate if you can help.
I am trying to create a form that participants can use to answer demographic qs.
My concerns are the following:
1.Do forms work on Pavlovia? Do certain ‘types’ work online and others not?
2.Can you explain why I keep getting this error?
I am using Psychopy3 (v2020.2.8) on windows10

Traceback (most recent call last):
File “C:\Users\Yasmine\Desktop\CSSL_Task\”, line 97, in
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\visual\”, line 118, in init
self.items = self.importItems(items)
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\visual\”, line 269, in importItems
items, fieldNames = importConditions(items, returnFieldNames=True)
File “C:\Program Files\PsychoPy3\lib\site-packages\psychopy\data\”, line 447, in importConditions
(fileName, len(trialList), len(fieldNames)))
UnboundLocalError: local variable ‘trialList’ referenced before assignment

Experiment ended.


I’ve recommend that you take a look at my demographics demo since forms are still in Beta.
