how to show shipping insurance

[romanj]

I'm a newbie to OS commerce. I need to show SHIPPING INSURANCE in page checkout_ payment.php. Please show me how to do this.

The following code:

 

<tr class="infoBoxContents">
          <td><table border="0" width="100%" cellspacing="0" cellpadding="2">
            <tr>
              <td><?php echo tep_draw_separator('pixel_trans.gif', '10', '1'); ?></td>
              <[b]td class="main" width="100%" valign="top"><b>Add Shipping Insurance? <input name="ship_insurance" type="checkbox" value="1" checked onClick="show_shipping()"></b><div id="shippingcost"></div>
//if checkbox Add Shipping Insurance is checked it will call function show_shipping() and will show the cost of Shipping Insurance
		  </td>[/b]
              <td><?php echo tep_draw_separator('pixel_trans.gif', '10', '1'); ?></td>
            </tr>
          </table></td>
        </tr>
<script> 
	function show_shipping(){
			   if (document.checkout_payment.ship_insurance.checked==true)
			   {
			   message_div = document.getElementById('shippingcost');
				message_div.innerHTML = "<strong>Shipping Insurance</strong> : C$([b]this place to show ship insurance[/b]) ";
			  }else {
			    message_div = document.getElementById('shippingcost');
				message_div.innerHTML = '';
			  }
			}
		</script>

 

I'm so confused. :'(
