I'm having an issue with my notification workflows when someone submits a new request through a form I created. I recently updated the 'Submitted By" field on the form to a drop down option so those submitting new requests can type their name and their email address auto populates. Previously, the field was left as open ended so the submitter would have to manually enter their email address. Since the update, I'm encountering a workflow error in which I'm not given an option to alert the person listed in the "Submitted By" field. My options are limited to other columns on my sheet.
The goal is to update the progress of their request.
