Label the window

{Dynamo1.3 、 Revit 2016}
I try to automatically label the window
And reference to this article

But there are still problems

Hope to provide a solution to the proposal, thank you

what is the error you are getting? You probably need to modify lacing or enable ‘use levels’ as you have 2 lists

Thank you for your reply

The error has been resolved

But i would like to ask how to automatically create a window label above REVIT?

What node should I use?
