tidy up your coding and replace with:
<tr class="spacer"><td colspan="6"></td></tr>

checkbox xhtml
<input type="checkbox" checked="checked" name="NAME!" />

and as for mail scripts first:

change ur form tag to <form name="email" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">

This will make your form post into the same document.

Then at the top add:

<?php
foreach($_POST as $key => $value){
$_POST[$key] = addslashes($value);
}
// tidied up the post and made it formatted .
mail(mail arguments);
?>
