This is a part 2 showing a way you can control whether a user can edit a field on a form (or in an app) based on the User() function and the Assigned To field (more dynamic and data-driven than in Part 1). In this case we expose a slight nuance in using ThisItem versus referencing a form control directly as well! It's really so easy to do!
