Floor.Plan.ByRoom node by archi-lab - combine multiple rooms

Hi @Kibar,

This is a very old topic. I ran into a problem with this graf, witch helps me alot. Thank you again for that. With new version of revit/Dynamo i cant find the Rooms by level made by Conrad/archilab. I dont know if he deleted it? Anyways I needed to do this process in another way. The copying, and collect rooms with same value in fsb lejemålsnr. works well, but I get an error (line 28) in the last costum node that should do the auto cropping. It retreive null value, wich I cant find. Can you help me out again? I attached the dyn graf as well.

Thanks!

Kind regards
Anders
