Wall type in Door schedule

Hi all,
first of all thanks for the daily support :slight_smile:
I would like to schedule the Doors host walltype, but i get an empty list. I have been looking around here and looks like it´s a well known problem, but can not get out of it.

Here is my script…
Any Help?

Im usin Revit 2020 and Dynamo 2

“Get Host Element” is returning the elements themselves, so you first have to get the ElementType before you can get its Type Mark:


Thank you very much! It´s working now!
