I am trying to build a product which is modular rather like a pc.

The costs per attribute are fine, and when the item is placed in the shopping cart the totals are fine also.

All attributes and option names have more than one option.

However once the item is in the cart, and you goto click on the item, to perhaps review it once more, i get an error message?

"http://www.iss-store.co.uk/catalog/product_info"

Not Found

The requested URL /catalog/product_info was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
