Please HELP! HTML/PHP form, checkbox recipients

[njfuller]

Hi all,
I have asked in several forums but have not yet found anyone who really knows how to do this.

I have a simple contact form on my website, using html form + php to send the info. I would like to make a change to the form, but do not know how to do it. The change is fairly simple, instead of having the form sent automatically to "[e-mail]" I would like the user to be able to select via checkboxes whether they send the info to "[e-mail]" "[e-mail]" or "[e-mail]" - or if they like... all 3

I have played and played but have got utterly lost, the php script for the contact form is below, I have made no changes and it works fine as it is - but just emails "[e-mail]" - could anybody please please please let me know how to make these changes to allow 3 checkboxes to select who you email? I will be so grateful for any help

Thank you!

<?php
$firstname = $POST['firstname'];
$lastname = $POST['lastname'];
$email = $POST['email'];
$message = $POST['message'];

$emailmessage = "Name: {$firstname} {$lastname}, with an email address of: {$email}, has contacted mycompany with the following message: {$message}";

$response = "Dear {$firstname},

Thank you for contacing mycompany, we have received your message and will respond within 24 hours.

Sincerely,

The Team";

mail($email, 'Your message to Mycompany',$response, "FROM:[e-mail]\r\n");
mail('[e-mail]', 'Message sent to mycompany', $emailmessage, "FROM:$email");

?>

create 3 checkboxes to the form, and use array variable names:

<select name="mail[]" value="1">First email<br />
<select name="mail[]" value="2">SEcond email<br />
<select name="mail[]" value="3">third email<br />

when you process the form,
check if the $_POST["mail"] has a selected email.

<?php


//store the emails in an array:

$emails=array("email1","email2","email3");

if ( empty( $_POST["mail"] ) )
		die( "Lets select an email" );
else
{
		$to = '';
		foreach( $_POST["mail"] as $recipient_number )
		{
				if(!empty($email[$recipient_number]))
				$to .= $email[$recipient_number] . ",";
		} 
		$to = substr( $to , 0, 1 ); // cut the last   comma
		// test if $to has a value before you send the mail...
} 

?>
