LPL - Initial Value - Populate a User Field from contents of a Base Class field

Patric

I have a User Field in Green and want to populate it with the Class Field contents in Yellow (initial value) where users would then add extra information as needed.

My LPL code below is not working and not sure why. Any ideas?

Look into “when value changed” rules.  Initial value rules only apply on a Create type action.
