I created a form for project tracking. The form has a project name field in it that is a required field. The manager fills that out first, but may go back later to fill in additional data. I created a button to allow them to search for a project name, but they keep opening the form and typing in the project name they want to search for in the project name field of the first record that appears. This changes or deletes the project name for the record they typed in. Is there a way to prevent them from typing in that one field after a project name is initially entered?
