How do you create an Arcade expression to reach out into other layers in the map to calculate values from another layer's features. These are the names of two layers in a map
EVER_FB_basinshorelines_Merge has an attribute field, "Island".
USGS_GEOL_FloridaBayShoals has an attribute field, "Name".
I would like to run the Calculate Field tool on "Island" to insert the values from "Name". The features in the two layers intersect but are not in the same database. What would I use for functions and syntax for the expression?
