Would it be better to accept edits using a form button instead? I understand what your problem is, but currently, what happens if you make a valid edit, and then a couple minutes later I make another valid edit to the same record. I would think that I would be taking the credit away from you because now my email address in in the record. This is irregardless if it’s a valid edit or not. That’s why I think a form button would be better. From there, I don’t know if it would be better to use a series of vlookups to find and update data or use zapier or scripting to take the last form submission and update the existing record.
