Form: Show a field only on edits (not when adding records)

[MarcosL]

Hello.
Consult I think elemetal, please:
How is it done so that some fields are not shown when generating a new record, but they are shown when that record is later edited?
Thank you. Marcos.

The following expression answers the question, does this row already exist?

IN([_ROWNUMBER], table[_ROWNUMBER])

This expression answers the question, is this a new row?

NOT(IN([_ROWNUMBER], table[_ROWNUMBER]))

In each, replace table with the table name.
