Annual Load Simulation Fatal Error caused by a zone name setting

I have made a very simple box office and tried to simulate an annual load calculation, but I got a fatal error message which says that "________________

zone" is not a valid Object Type.

I guess it might be caused by a room(zone name setting), but is there any advice for it?

Thank you. (121.1 KB)

hi @ecoville There is a space in the name after "Office ". Delete it.

Thank you @Asisnath !!
