Ok, so I looked up this up a bunch of places, but none of them could really solve my issue, which is suprising, because it seems pretty simple...

I have a very basic ajax email form, and I just can't figure out how to handle the checkboxes in it. It would be great if I could have the email send the values of the checkboxes if they are checked (for example, if there were checkboxes 1,2, and 3, if only 3 were checked, the email would display "boxes checked: 3"), but if not, it's not a disaster to have each box even displaying a true or false value.

Here's my PHP, and here's and example of the page... I hope someone can help me with this?

Code:
<?php
	//declare variables
	$name = $_GET['name'];
	$title = $_GET['title'];
	$company = $_GET['company'];
	$address1 = $_GET['address1'];
	$address2 = $_GET['address2'];
	$city = $_GET['city'];
	$state = $_GET['state'];
	$email = $_GET['email'];
	$telephone = $_GET['telephone'];
	$fax = $_GET['fax'];
	$dial = $_GET['dial'];
	$auto = $_GET['auto'];
	$comptel = $_GET['comptel'];
	$other = $_GET['other'];
	$overall1=($_GET['a1'])?"Yes":"No";
	$app=($_GET['a2'])?"Yes":" No";
	$overall2=($_GET['a3'])?"Yes":"No";
	$see = $_GET['purchase'];
	$list = $_GET['MailingList'];
	$subject = "Demo Request from Website!";	
	$message = " Contact Information: \r \n Name: $name \r \n Title: $title \r \n Company: $company \r \n Address: \r \n $address1 \r \n $address2 \r \n Location: $city , $state \r \n Email: $email \r \n Phone Number: $telephone \r \n Fax: $fax \r \n \r \n Interested in... \r \n Predictive Dialer? = $dial \r \n Auto Dialer? = $auto \r \n Computer Telephony? = $comptel \r \n Other: $other \r \n \r \n This person wants to see: \r \n Overall1: $overall1 \r \n Overall2: $overall2 \r \n App: $app \r \n This person needs a solution: $purchase \r \n \r \n Add to the mailing list? $mailinglist";
	
	mail("escalantejeff@gmail.com", $subject, $message);
