Welcome @victoriano8924C  
The warning is telling you that the parameter you are trying to write to does not accept string values. It only accepts numerical values. In the video, they are writing to the “Department” parameter which does accept string values.

In your graph, not sure where the String from Object is coming from, but you can write that to the “Name” parameter of each room. Of course that will show up on the plan view.
