Help posting contents of Flash form to mySQL DB via PHP

I have created a flash site for me and my fiance’s upcoming wedding. I have created a flash from so that we can collect the addresses of our guests.

Currently the contents of the form are emailed to me. I have created a mySQL DB with id, name, address, and email. I would like to have the contents of the form posted to the DB as well as emailed. I have tried to utilize numerous tutorials to get it to work but I have spent many hours without success. I was hoping that somebody would be willing to take a look at my PHP script and tell me if they can find what my problem might be. The email portion of the script works fine. The only things I have changed in the script are DBhost, DBuser, DBpassword, everything else is exactly as it appears in the script I have been testing. It may be something really simple (hopefully). I would really appreciate the help. My PHP and SQL knowledge are both quite limited.

Please feel free to peruse our site. I would love to have some feedback. Thanks in advance.
