Room number to floor parameter


I am trying to enter the parameter of the room number in a floor and ceiling parameter. Does not work. What’s my mistake. With windows works without problems. Ceilings can not see at all (((
Thanks in advance for your participation!

Has someone already found an answer to this question? I’m looking for the same dynamoscript.
I’m having separated finished floor for each room and know I want to send information (for example the room number) to a floor parameter.
