Help with PHP submit form

[ponyman]

hmmm. the form works if I don't fill it out and just click submit, I geta a blank e-mail

here is the .php file

<?php

// Capture info sent from the form in variables


$Title = $_REQUEST['Title:'];
$URL = $_REQUEST['URL:'];
$Category = $_REQUEST['Category'];
$Type = $_REQUEST['Type'];
$Comments = $_REQUEST['Comments'];
$nickname = $_REQUEST['nickname'];
$email = $_REQUEST['email'];


// Print out one of the vars on the page just to make sure you got it

echo "Thanks for submitting to The Sexwitch! You will receive an e-mail about your site once it has been reviewed. $message<BR>";

// Email it to myself

mail('sexwitch@sexwitch.com', $Title, $URL, $Category, "From: $nickname ($email)\r\n");
?>
