using product name in the url is causing a problem

Hi

I have a child portal set up where some of the products are a direct copy with minor localisation changes of the products in the parent portal i.e. the product name "Product A" exists in both portals.

When airicie and the module specific (${BASE_REPLACERULE_ROOT}[/${ProductName}]${BASE_REPLACERULE_END}) rules are enabled it seems to display the product details of whichever product was last updated in the database. When they are turned off it goes to the correct product details.

Any suggestions? I am assuming I need to add something to the rule to give it a unique identifier?

Thanks in advance.
