PHP Code:
function check() {
      if (!isset($this->_check)) {
        $check_query = tep_db_query("SELECT configuration_value FROM " . TABLE_CONFIGURATION . " WHERE configuration_key = 'MODULE_ORDER_TOTAL_REDEMPTIONS_SORT_ORDER'");
        $this->_check = tep_db_num_rows($check_query);
      }

      return $this->_check;
    } 
How can i make the above code zen-cart compliant??
I have read the wiki...
I am having trouble replacing $this-> check

Hoping to get a reply
Thanks
