Just use this command as the others would have already been processed:

PHP Code:
INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, set_function, date_added) VALUES ('Telephone Number', 'ACCOUNT_TELEPHONE', 'true', 'Display telephone number field during account creation and with account information', '5', '8', 'zen_cfg_select_option(array(\'true\', \'false\'), ', now());
