Contact form not working/PHP

Thanks for the replies so far – basically the form redirects to a PHP page which originally used this script

<?php

$ip = $_POST['ip'];

$httpref = $_POST['httpref'];

$httpagent = $_POST['httpagent'];

$visitor = $_POST['visitor'];

$visitormail = $_POST['visitormail'];

$visitorphone = $_POST['visitorphone'];

$address1 = $_POST['address1'];

$address2 = $_POST['address2'];

$city = $_POST['city'];

$state = $_POST['state'];

$zip = $_POST['zip'];

$notes = $_POST['notes'];

if (eregi('http:', $notes)) {

die ("Do NOT try that! ! ");

}

if(!$visitormail == "" && (!strstr($visitormail,"@") || !strstr($visitormail,".")))

{

echo "<h2>Use Back - Enter valid e-mail</h2>\n";

$badinput = "<h2>Your message was NOT submitted</h2>\n";

echo $badinput;

die ("Go back! ! ");

}

if(empty($Name) || empty($email) || empty($textarea)) {

echo "<h2>Use your Back button - fill in all fields, No message was sent.</h2>\n";

die ("Use back! ! ");

}

$todayis = date("l, F j, Y, g:i a") ;

$subject = Contact_from_your_webpage;

$notes = stripcslashes($notes);

$message = " $todayis [EST] \n

Message: $notes \n

From: $visitor ($Name)\n

From: $visitor ($email)\n

Additional Info : IP = $ip \n

Browser Info: $httpagent \n

Referral : $httpref \n

";

$from = "From: $visitormail\r\n";

mail("xxxxxx@xxxxxxxxxxxx", $subject, $message, $from);

//check if form was sent

if($_POST){

  $to = 'xxxxxx@xxxxxxxxxxxx';

  $subject = 'Testing HoneyPot';

  $header = "From: $name <$name>";

  $Name = $_POST['Name'];

  $email = $_POST['email'];

  $textarea = $_POST['textarea'];

  //honey pot field

  $honeypot = $_POST['firstname'];

  //check if the honeypot field is filled out. If not, send a mail.

  if( $honeypot > 1 ){

  return; //you may add code here to echo an error etc.

  }else{

  mail( $to, $subject, $message, $header );

  }

}

if($_POST['nospam_field_name'] != ''){

  echo "It appears you are a spambot! Form processing aborted";

}

else{

//process the rest of the form

}

?>

<p>

Date: <?php echo $todayis ?>

<br />

Thank You : <?php echo $Name ?> ( <?php echo $email ?> ) 

<br />

Message:<br />

<?php $notesout = str_replace("\r", "<br/>", $notes);

echo $notesout; ?>

<br />

<?php echo $ip ?>

I did realise just now that one other issue is the idea was it was supposed to redirect to a thank you page when the form was successfully sent – I did see Nancy's tutorial on forms and PHP
