I created a form using Coffee Cup's Flash Form Builder (php I believe) and it appears to be not working. When I test it and hit "submit" I get the following message:

Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in D:\Inetpub\headingwest\puntpassform.php on line 163
Cannot send email!
Either sendmail or smtp is not properly configured on your system.
Please contact your hosting provider to correct this problem.

The form is on this page: http://www.headingwest.org/invite.html

I know absolutely nothing about scripting (hence the use of the form builder), so please reply as if I am a kindergartener Any ideas?

Thanks so much!
