Alarming expression

I’m trying to write expression in tags alarming label to assign label from its tag path. Using following expression

Same expression is working in normal text field container but in tag itself, it’s not working.

------Reason for expression.---------
I’m trying to give label a name (expression will be UDT) same as the parent folder that tag resides in.
for eg.
#tag path: Unit 1/Folder 1/Folder 2/Bit Status/Auto
So with above expression, label for tags alarm will be “Folder 2”.

As i’m using UDT, I want a single expression that will apply to all its child tags alarm.

Nevermind, it worked when I used {itemPath} instead of {displayPath}.
