HTML editor error Line 1 in configuration.php ???

[blind1]

I want to get this working. Maybe I accidentally changed something.

Fatal error: Call to undefined function: zen_cfg_pull_down_htmleditors() in /home2/creativ/public_html/aussiedog/AdminXXXX/configuration.php(192) : eval()'d code on line 1

Does anyone know what error in line one may be?

This is the first few lines:

add_session(ERROR_ADMIN_DEMO, 'caution');
          zen_redirect(zen_href_link(FILENAME_CONFIGURATION, 'gID=' . $_GET['gID'] . '&cID=' . $cID));
        }
        $configuration_value = zen_db_prepare_input($_POST['configuration_value']);
        $cID = zen_db_prepare_input($_GET['cID']);

        $db->Execute("update " . TABLE_CONFIGURATION . "
                      set configuration_value = '" . zen_db_input($configuration_value) . "',
                          last_modified = now() where configuration_id = '" . (int)$cID . "'");
        $configuration_query = 'select configuration_key as cfgkey, configuration_value as cfgvalue
                          from ' . TABLE_CONFIGURATION;

        $configuration = $db->Execute($configuration_query);
