Change Nav Bar title to Match info box title

I have a few pages outlined in mt Information Box and additional information Box.
For example I have a paaage called Warranty & Returns in the Information box, When I click and open it the Nav bar ends with =conditions. Same applies to Pages 3 and 4. I would like to change this to represent the name of the pages.

I.E. ==Warranty
Page 3= Corporate Sales
Page 4 = Recycle.

I have searched High and low and can't seem to find appropriate pages. My other tiotles are all OK except these 3.
Thanks in advance for your help.

Get and review thse add ons for the eight files that must be created/edited for a new page that will be represented by the page name
http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=182
http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=1125

I've added the about us page module to my site.
I have added $information[] = '<a href="' . zen_href_LINK (FILENAME_WARRANTY_RETURNS) . '"> . BOX_INFORMATION_WARRANTY_RETURNS . '</A>':
inthe information.php file. The Warranty & Returns in the sidebox comes out as BOX_INFORMATION_WARRANTY_RETURNS. and when I click on it it gives me a unable to locate page error.

Where do you think I went wrong?
I changed all instances of about_us to warranty_returns, and re-named the php files to WHERE ABOUT-US was located to warranty_returns as well.
Thanks again,
Bob

I have rectified the problem with the BOX Info.
All I have left is the problem with locating the Warranty & Returns page. It comes back with a Page Not Found Error.
Any Suggestions Please.
Thanks again,

Does anyone know where I have to go to rectify the fact that my Warranty & Returns page-(page is About us Module) will not come up. I get a Page not found Error message. I'd like to get this fixed before adding additional Information sheets.
thanks,
