Thanks, these do mostly solve the problem. Also, simply using [cgi
name="gift_note"] in the text area  instead of [value gift_note] seems
to work too.

It still doesn't seem quite right, though.  If a customer fills in the
note field, presses "Recalculate", decides to shop some more, then
goes through checkout again, the note they entered is gone.

It seems better to clear the gift_note value from the session after
the order is placed. Is there a good way to do this?
