I installed the contribution and everything works fine. However, the system doesn't seem to accept names with apostrophes (i.e. O'Hara. D'Alessandro, ecc.). To make it work, I had to cut off from admin or the database all the apostrophes. More precisely, when a customer fills out the form to send someone a gift voucher, in the next page - before the email is sent - he/she sees the name of the recipient with a slash (i.e. O'Hara turns into O\'Hara, D'Alessandro into D\Alessandro, etc.). Thi is not nice to see. Then, when hitting the button send, the next page displays an sql syntax error referring to the "coupon_email_track" field. The problems address the "sent_lastname" field, of course. I haven't encountered this problem elsewhere in oscommerce ms2, 'cause names with apostrophes are accepted. Any clues?
