VB rule to default value based on two parameters

Hello Experts,

I have the following requirement in a Redwood quick action (configured via VB Studio Express mode, "Configure Fields and Regions").

I need to default the value of a custom DFF segment at Assignment level based on a cascading logic that reads from two different source fields:

1. First, take the value from the corresponding DFF segment at Job level.
2. If that value is blank at Job level, fall back to the same DFF segment at Department level.
3. If both are blank, leave the field empty and editable.
