I created a workflow to update a list (
Rooms) when another list (
People) is changed. I want to assign a value in the
Room column in
People list and have the value in column
LastName be added to the
Occupant column in
Rooms. I've tried several iterations, and keep getting an error that has no meaningful information (at least to me).
Any idea what this error means or what I'm doing wrong? What value can't be null? Isn't that what I'm checking for in the first step? As a first-time Sharepoint user, I'm really discouraged by how difficult this simple task seems to be.
