β@Grace β@nhutaj28 - one possibility is to send the previous answers into the form as url variables, and display them in the question description ie You previously answered @hidden_var_one β¦. and then ask them if they want to update. if yes record the new data otherwise use the original value as your input.
if you connect the form to a Google Sheet, as β@Grace mentions, then you would have a second row of data (or more) depending on the number of times you have the user submitting the form.
one thing to keep in mind is to determine which set of data you want to send to the user - if they have multiple responses β¦ ie a quarterly update might have 3 or 4 updates,so which one to use to populate the hidden variables (per my example)
i tend to use Google Sheets and Document Studio to send out the βlast versionβ of the data received in a custom report and with the link to the file - the url string is built in the google sheet record and Document Studio sends the most recent url link string to the user .
just a thought
