You should change the checkbox names, they are all the same now (each checkbox name has to be unique). PHP code to identify whether a checkbox is checked, use:
[php]if(isset($_POST['checkbox_name'])) echo 'checked';[/php]

You need to post the form.

myform.php
[PHP]

[/PHP]

check.php
[PHP]
<?PHP
if(isset($_POST['cd0'])){ echo 'checked';}
?>
[/PHP]
