Hi, great script! Do you have a version of the last screen-shot that you want to share? We keep getting an error on the node for RoomAtPoint, “This custom node contains an invalid input. Please fix the input before saving the custom node”. Thanks for the help.
Hi @bettina.h.andersen …dont have it anymore but should be pretty easy to rebuild, just follow the image…if it still doesnt work then share your graph and your family and i will take a look 
best if you start a new topic as this one is already solved. PS just test it it works fine from here…whitch revit version are you on ?..hmmm probably i should read the post before i answer sounds like you just should open the node and rename Phase to phase and it should work…hoppefully
