Expression syntax

What s the expression syntax for the new “restrict adding counters by Drag 'n Drop” in 3.2?

I have markers set on each of my cards that denote the deck they belong to:
Marker - >
Property Name: Deck
Property Value: Workers

Now, how do I set that in the drag and drop to allow those cards to be dropped there?
It tried the old way: Deck: Deck=Workers
I tried using the expression thing: Workers_marker: Deck=Workers

I have no clue.


I use markers too for that and just the equivalent of Deck==“Workers” works for me.


Dur! Yep. Worked a charm!

Thank you!
