I have respondents complete a survey, this survey then reports via email to a person who process the responses. The respondent can however go back via a retake link and amend any of their responses. When they do this the same report is generated via email and at the top of the email is indicates this was taken via a retake link. My questions however is there a way to determine what answers were changed in the retake so the person receiving the report via email doesn't have to compare surveys to find the differences? Thank you.
