Hi Josh,
I've tried to work with this method you explained. Let me show you the steps i did with the help of some screenshots.
First, I set up a trigger on my map as you did:
![VictoriaJadot_0-1662562131829.png VictoriaJadot_0-1662562131829.png](https://community.esri.com/t5/image/serverpage/image-id/50635i284B8A2FBCCABBD4/image-size/medium?v=v2&px=400)
Next, I make a list and select 'selected features':

Next, i put the name of the selected features as dynamic content:
![VictoriaJadot_2-1662562285839.png VictoriaJadot_2-1662562285839.png](https://community.esri.com/t5/image/serverpage/image-id/50637i59E208A0F2094BE4/image-size/medium?v=v2&px=400)
Now the problem that i am facing is the following: the list doesn't update when clicking on a building, so the trigger is not working. I keep getting the 'No data' sign on my application:
![VictoriaJadot_3-1662562542049.png VictoriaJadot_3-1662562542049.png](https://community.esri.com/t5/image/serverpage/image-id/50638i5E655AD134F10C7C/image-size/medium?v=v2&px=400)
Important to mention maybe: The S13 buildings layer is a 3D scene layer and the S13_train layer is a 2D feature layer. These two layers are also not in the same web scene, i don't know if this is a problem or not?
Do you know how to make the trigger work in this case? Thank you in advance and best regards,
Mauk
