Mail script error checking problem

Hi, I have a form mailer that I'm completely stumped on. It landed on my desk and I can't figure out what's wrong with it. It continually gives me empty field errors even when they're populated and won't send the email.

I'm sure someone here will have it sorted out in ten seconds but I'm more of a graphics guy and I'm just not seeing what's wrong. Any help would be appreciated!

Thanks in advance!

<?php
 
function createForm() { // grab variables from posted form, if any exist
	$name = $_POST['name'];
	$phone = $_POST['phone'];
	$email = $_POST['email'];
	$comments = $_POST['comments'];
 
 
	// build the form, populate the fields if needed
	echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="POST">
	<p>FULL NAME:<br />
	<input name="name" type="text" id="name" size="40" value="' . $name . '"></p>
	<p>TELEPHONE:<br />
	<input name="phone" type="text" id="phone" size="40" value="' . $phone . '"></p>
	<p>EMAIL ADDRESS:<br />
	<input name="email" type="text" id="email" size="40" value="' . $email . '"></p>
	<p>QUESTION/COMMENT:<br />
