Hi, again.
As I said before, I can try some steps in js but definitely that isn’t my ground, i.e., I don’t have code knowledge.
I can look to your attempts and say some things:
if we want to target a created field (not an implicit field) we don’t need to add the prefix file: not dv.current().file.Parent but dv.current().Parent
if values are “links” we need to work in different way (links aren’t “strings”)
With all my obvious limitations, I can suggest this:
But this seems to work only if you have only one value in Parent::… if more than one link this doesn’t work.
As you can see my effort stops in simple things like «how to solve this if a list/array»?
