Follow Up to a previous support request

I'm not sure if my first support request went through...

I am trying to get the Shopping cart to work... I've set up some Categories that I'd like to come back on the 'Order Online" page (in the navigation) I put this short code on that page: [mp_list_categories]

Even though I have my Categories defined... the list is not being retrieved.

I will put products up, for each category... when I see that the listed categories are displaying

Also, the pages that were supposed to be automatically created during the Setup configuration don't seem to be there.
