Hi,

first of all - are you sure that the php file is called with a valid http:// address from the swf
Can you test the php from a browser? If your movie is sending vars like name, email, message as GET parameters, you could enter
http://example.com/mail.php?email=me...essage=testing
into a browser and see what happens. If you are using POST, you would nee to create a simple html form and use that in browser

Is this intended for a kiosk application, or are you actually expecting people to run some weird exe files just to be able to communicate?
