Routes help

[eluser]PHP Creative[/eluser]
Hi

I was wondering if anybody could help me. I have the following url.

http://www.test.com/store/dvds/34

store = controller name
dvd = category name (hundreds of possible categories so would be hard to create an array)
34 = id of product

Basically I can route the first URI (category) to a function inside store called categories doing the following

$route[store/(:any)'] = "store/categories/$1";

But can’t re-route the product id to a function called product_info. Tired the following:

$route[store/(:any)/(:any)'] = "store/product_info/$1";

I would really appreciate any help.

Thanks a million
