Beginner needs help- simple 'mail_to' contact form in PHP

Hi all! ... I used TrendyFlash Site Builder to create a site, which generated a 'contact.php' file that I need to modify.
Basically it calls for the user to send a comment with a name, email id, subject and message. I need it to send those details to an external email id that I specify. Here's the script as generated by the software in that 'contact.php' file :

<!-- script starts here-->
<?

$contactfield1=$HTTP_GET_VARS["contactfield1"]
$contactfield2=$HTTP_GET_VARS["contactfield2"]
$contactfield3=$HTTP_GET_VARS["contactfield3"]
$contactfield4=$HTTP_GET_VARS["contactfield4"]

$email_from = "[email protected]";
$email_subject = "" ;
//$email_txt = "";
$email_to = "[email protected]";

$email_message = "field1: $contactfield1\n
field2 :$contactfield2 \n
field3 :$contactfield3 \n
field4 : $contactfield4 \n

";

mail($email_to, $email_subject, $email_message,$email_from);

?>

<!--script ends here-->

OK ... i went through some sample contact form scripts online and modified it like this :

<?php

// I should think the following 4 lines correspond to the 4 fields indicated in the screenshot attached at the end
// of this message

$contactfield1=$_POST["name"]
$contactfield2=$_POST["email_from"]
$contactfield3=$_POST["subject"]
$contactfield4=$_POST["comment"]

$email_from = "";
$subject = "" ;
//$email_txt = "";
$email_to = "my email id here";

$message = "field1: $contactfield1\n
field2 :$contactfield2 \n
field3 :$contactfield3 \n
field4 : $contactfield4 \n

";

mail($email_to, $subject, $message,$email_from);

?>

So is this right ? I uploaded it to test it, but it doesn't seem to work as I'm not getting anything in my email box.
If I can only get this script right, I can apply it to all future sites that I create using this software. So I just need to get it right once. This software isn't designed for scripting- PHP or otherwise, so it needs the user to know PHP if he wishes to go by that route (else I'd have to only publish the site to CD). Also if it requires any proper formatting (as some lines in the script seem to me to be out of place), then provide that too.

Any takers?
