How do I copy individual instances from subform table to mapped text fields?

[brianmjohnnies]

I am creating a letter. I have a table created that adds or deletes a row for each person in a family. I am asking each person to sign an agreement so I need to map the individual persons filled in the instance(s) to text fields. If 10 persons are in the table I need each of 10 text fields to fill with the instance values. How do I identify the unique instance - grab the value and copy to text fields?

It would help if you post screenshots of your form and its hierarchy or when you share your form.
