What are you trying to achieve?:
I want to use the form component to create a scale.
What did you try to make it work?:
I used the excel template in the forms component, as follows:
What specifically went wrong when you tried that?:
this is the output of PsychoPy Runner

Thank you
The issue lies in the ‘a,b’ within the options. You need to add a space after the comma, making it ‘a, b’. If the format is not like this, it will result in an error.

Since some components of psychopy are still in beta testing, the form component comes with a scale template that has formatting issues, so you can either save the format as a .csv or look for a template file that doesn’t have formatting issues.
What input have you given it? "1,2" might be a suitable string. 1.2 is a decimal
What does your form item file look like?
Remove the tick from after the final tickLabel
I tried to remove it from ticklabels, but it was still wrong.But when I used the form that someone else had sent me, the problem was solved.Maybe there’s something wrong with the form I downloaded.
Thank you for taking the time to help me.
