title: Accessing field data from table in a deep structure?
body: <p>I would like to access data from the (in image) highlighted field ID from item table, which exists in a deep nested structure.
  I'd then perform various checks if whether the data is initial. In other cases, I'd actually pick data from one of these fields, and input in another field of another table in the deep structure.</p>
