categories tabs v2.0 installation trouble

[Cerrak]

Hello,

 

I have downloaded and trying to install the category tab contribution in the header.

 

I have done everything but step 1 which is:

 

1. Add the following to the database:

INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, date_added, use_function, set_function) VALUES('Category Tabs', 'CATEGORY_TABS', 'Tabs', 'Choose to have category tabs, the category box on the left, or both.', '1', '2', now(), '', "tep_cfg_select_option(array('Tabs', 'Box', 'Both'),");

 

Whats php document do I do this? and where?

 

right now, my tabs are all in one line which is about 3 times the width of my website.

 

any help anyone could provide would be appreciated.

 

Thanks

 

P.S. I dont use sts with my site.
