Filtering dynamic content by category url

Hi,

We are using a dynamic module which has several custom classification called "industries", "franchise" and "location". In the list view on the front end we want to be able to filter the list view by these category url when the user clicks a link. I thought this was built in but it is not working.

So for example, the page with the list view that shows all the content items is: 
"/businesses-for-sale"

When the user click the industry link for "Domestic Services" it loads the url path "/businesses-for-sale/-in-industry/industries/domestic-services" and it should filter those items associated with this classification.

But instead it gives a 404. You can see the example here: www.jpabusiness.com.au/businesses-for-sale - clicking on the "Business type" should filter the list.

Am i missing something?

Thanks.
