Get items placed in model based on location in linked file

Hi

I’m currently trying to set up a script which allows me to write the room number into a family if the family is placed in the room.

The room are located in a linked model and the family is placed in the “native” model.

Any way that, that is possible? Currently I’m getting the following?

Pls use search.

Que?
