"No email address for this receipt: add one to the adult student's record or to a parent's."

Where: student profile, Payments card, Send receipt or Resend buttons.

Why: the receipt goes to the adult student who has an email; for a child (or an adult without email who belongs to a family), it goes to the first parent in the family, in the family's order, who has an email. Here, nobody has an address. Nothing is sent and no receipt number is used. The payment status shows "Not sent: no address".

What to do: the owner adds an email to the adult student's record, or to a parent in the family, then sends the receipt again from the Payments card. Instructors do not see contact details: they ask the owner to fill them in.
