The reason your code didn’t work is that Qualtrics renders the group headers dynamically and wiping them out with innerHTML = "" breaks the question’s logic. The safer approach is to append an input field under each header instead of replacing it, and then capture what the respondent types into Embedded Data or a hidden field. That way the default group labels stay intact for Qualtrics, users can rename them during the survey, and you still record their custom names in your data.
