SQl Query error

[dmiles]

I am installing the Minimum Product Quantity with Admin found at:
http://www.oscommerce.com/community/...ns,2953/page,2.

When I try to run this query:

INSERT INTO `configuration` (`configuration_id` , `configuration_title` , `configuration_key` , `configuration_value` , `configuration_description` , `configuration_group_id` , `sort_order` , `last_modified` , `date_added` , `use_function` , `set_function`)
VALUES ('500', 'Minimum Orders', 'MINIMUM_ORDERS', 'true', 'Whether or not to enforce minimum orders', '1', '19', NOW( ) , NOW( ) , NULL , NULL);

I get this error:

#1062 - Duplicate entry '500' for key 1

I ran another query from the contribution successfully so, I think that I am using the correct procedures.

Can anyone help me with the syntax of the query causing the error?

Thanks for your help!

VALUES ('500'

500 is already used. Change it to another higher number and try again. Try 800. Should work..

Ask for help when install this mod, after run sql in phpmyadmin

INSERT INTO `configuration` (`configuration_id` , `configuration_title` , `configuration_key` , `configuration_value` , `configuration_description` , `configuration_group_id` , `sort_order` , `last_modified` , `date_added` , `use_function` , `set_function`)
VALUES ('', 'Minimum Orders', 'MINIMUM_ORDERS', 'true', 'Whether or not to enforce minimum orders', '1', '19', NOW( ) , NOW( ) , NULL , NULL);

**then returns**
