	function createAddress($vars,$userid) {
		
		if (empty($userid) )
			return false;
		else {
			
			$db = JFactory::getDBO();

			if(!empty($vars['PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE'] ) ) {
				
				$db->setQuery('SELECT zone_namekey FROM `#__hikashop_zone` WHERE zone_code_2 = '.
				$db->Quote($vars['PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE']).' AND zone_type = \'country\';');
				
				$country = $db->loadResult();
			}
			
			if (empty($country) ) {
