I don't know if this is possible,
I have been searching online and can't find a solution but how would I go about keeping changes to a form and then having an update form. My boss wants me to add a field to a form and it will be auto generated a letter or number such as "A" or "1". Then if lets say the form changes because the user wants to change something, for example its now an estimate for a request when before it wasn't, so the user changes the form to not an estimate, then the field on the form goes to "2" or "B" and saves it as a new record. So now people viewing can review the old form and the new form with changes made linked to the same id and see the changes made on the new form while having the old form as well.
Thanks, all help is appreciated!
