We have a few questions using display logic. once the hidden questions are displayed I want them to become required. I dont seem to be able to make that happen just using the "Force response" button i end up getting the error "This option is not compatible with questions containing in page display logic.". Is there a workaround? Thank you!

What is the type of your hidden question. Also do you want to display question within same page. As few questions are not compatible with inpage display logic.
