breadcrumb navigation 'top' link points to incorrect page

[tidysi]

Hello

 

On one of my pages I have the following breadcrumb navigation

 

Top » Catalog » DW Merchandise

 

Catalog points to the main oscommerce index.php - which is OK, but also Top points to an index.php even further up onto the main site

 

i.e. Catalog -> http://www.site.co.uk/ecommerce/shop/index.php

 

Top -> http://www.site.co.uk/

 

Where can I change Top to point to the same as Catalog?

 

Many thanks
