Set coordinates as instance parameter "Mark"

Hi all - I am trying to create a script that reports the coordinates of a symbol and sets the instance parameter “Mark” that I created based on these values. The problem is it runs only on one instance of all symbols and all others are left blank. I am also trying to set the value to 2 decimal places.

I am new and very frustrated

Your list structures don’t match. You have one list of elements (@L2) and a list of sublists of coordinates (@L3). You should just need to flatten the list of coordinates.
