Problems with email script

[AdRock]

Hello

I am new at PHP and am stuck
I have got an email script that should send the contents of a feedback form via email but when testing it I get an error message.

Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in D:\Apache2\htdocs\feedback.php on line 94

Warning: Cannot modify header information - headers already sent by (output started at D:\Apache2\htdocs\feedback.php:94) in D:\Apache2\htdocs\feedback.php on line 95

Is there something I should edit that will make this work?

I have enclosed a file with my feedback html file and the feedback php script.

Any help would be very appreciated.....thanks

you don't have sendmail set up properly for php. If it's not your own server, you're screwed I believe.
