I am trying to get doors to display the room number they open into in their door marker. I have set the door marker's text to display the "Room ID" and have checked the box "Door belongs to the zone into which it opens". However, The marker remains blank. I can't seem to get it. I have checked in a schedule, and it appears that the door knows which zone it is going into, but I can't get the Room ID to show in the marker. Thanks!
