Magento

Hi,
i am customizing checkout method.
How do i add new functionalities in Payment Method of Checkout as shown in attached image.
In attached image, i have added 2 radio button to get an input from user about
“whether an Credit card Address is same as shipping address” ? Yes / No.

i have added 2 checkbox in template/paypal/standard/form.phtml
<input name=”cc_add” id="cc_add" type="radio" value="yes" onClick="” CHECKED>Yes</input>
<input name=”cc_add” id="cc_add" type="radio" value="no" onClick="">No</input>

In savePaymentAction():
i have added below lines:
$CC_add = $this->getRequest()->getPost(’cc_add‘, ‘’);
$result = $this->getOnepage()->savePayment($data,$CC_add);

In Onepage.php
public function savePayment($data,$CC_add)
{....}

i dont know how to proceed from here..

Plz correct me if i m wrong.
