I am an InfoPath person so I am used to using rules!
I have a field called "Current Status" which is a drop down list with "Approved" or "Rejected".
What I am trying to achieve is when a user selects the status, e.g. Approved, that the following field "User name (A people picker field) is updated with the Current User.
In the example below, I select "Approved" but then searched my name....I want the action of selecting "Approved" to populate the User field with the CurrentUser.
