Having a blonde moment. How would I show (as a field) the customer’s (numeric, auto-increment) internalid of the record (entity) on the customer form?

New field for internalid (view) set by script or workflow aftersubmit is what I normally do.

If I understand your question correctly: custom entity field. Don't store value. Default value = formula = {id}

weird that I can’t just SHOW the field

Jen, I'm assuming you know that it's in the URL as well, right?

Yeah for sure. My team was asking if there's a "better" way to get it than from URL as they are worried they will copy paste wrong.
