Joomla 1.5.26, VM 1.1.9

Hi.
After applying the frontend Hack i get following Error Message when i go to the account maintance area.

Parse error: syntax error, unexpected T_STRING in XXXXXX/administrator/components/com_virtuemart/classes/ps_order.php on line 727

Line 727 is bold

$pdf_url = "index.php?option=com_vminvoice&controller=invoices".
"&task=pdf&cid=".$db->f("order_id");
$tmp_cell = ($db->f("order_status") == 'C OR $db->f("order_status") == 'S') ? '<a href="'.
JRoute::_($pdf_url).'"><img src="'.JURI::base().
'plugins/editors/jce/tiny_mce/plugins/filemanager/img/ext/pdf_small.gif" '.
'/> '.JText::_('Invoice') .' </a>' : '';

Thank you.
