Find the z value of floor above

Already found what I was looking for:

Identify floors just below rooms

Hi All, I have created all the finish floors for my project and need to transfer room data into them but I couldn’t find a way to identify what floors belong to what room. I have tried to identify them by using the room boundaries node but floors are not included in the results. Any idea how to achieve this? Thanks!

Thanks for the input!
