Problems capturing form data

Question

I'm new to PHP and I'm having a few problems. I've put
together a script to process an HTML form and I need it to capture
the names of all 'checked' checkboxes within my form and exclude
all unchecked data. I know i must be doing something stoopid but i
can't work it out. I just get a list of all items with their value
next to them if checked. Any help would be really appreciated.
Thanks. Here's my script:
<?php
/* Subject and Email Variables */
$emailSubject = 'Subject';
$webMaster = '[email protected]';
/* Gathering Data Variables */
$A = $_POST['A'];
$B = $_POST['B'];
$C = $_POST['C'];
$D = $_POST['D'];
$total1 = $_POST['total1'];
$total2 = $_POST['total2'];
$total3 = $_POST['total3'];
$total4 = $_POST['total4'];
$total5 = $_POST['total5'];
$day = $_POST['day'];
$email_address = $_POST['email_address'];
$comments = $_POST['comments'];
$body = <<<EOD
Item A: $A <br>
Item B: $B <br>
Item C: $C <br>
Item D: $D <br>
<br><hr>
Price  $total1 <br>
<hr><br>
Data A   $total2 <br>
Data B   $total3 <br>
Data C   $total4 <br>
Data D   $total5 <br>
<br><hr><br>
Ordered For:   $day <br>
Email Address:   $email_address <br>
Instructions/feedback:   $comments
<br>
EOD;
$headers = "From: $email_address\r\n";
$headers .= "Content-type: text/html\r\n";
$success = mail($webMaster, $emailSubject, $body, $headers);
/* Results rendered as HTML */
$URL='
http://www.xxx.com/thanks.html';
header ('Location: '.$URL);
?>
<td><input name="A" onClick="change(this)"
value="160g" type="checkbox"></td>
If its relevant, onClick="change(this)" relates to:
<script type="text/javascript">
function change(obj) {
var tr=obj.parentNode.parentNode;
if(obj.checked) {
tr.className+=' pink';
else {
tr.className=tr.className.replace(' pink', '');
clickCh();
Please can someone explain where i'm going wrong?
Thanks
