Need help with form_multiple_choice
please excuse if my question is very basic, but I am having a hard time with the form_multiple_choice_form.
I know how to set it up and record the variables, but I would also like to force the subjet to make a response.
I am currently using a multiple force form with "allow_multiple no" and "advance_immediately no", as I want subjects to have time and change their mind before proceeding to the next item.
My big problem though is, that subjects can also advance to the next item by pressing "ok" without selecting an option before. It's a huge risk as some of the test will have to be administered remotely and I might lose a lot of data.
Is there any way I can force the subject to make a decision before proceeding? Maybe some inline_script or something?
I don't really know how to code, but if you can at least point me in the right direction, that would be a great help!
Thank you in advance,
