DNN6.0.1 Smith Shopping Cart 4.6 (Trail Version) 

I have a page setup called Product Detail,

I have the Product Detail module on the page,

In the main settings I have Product Detail set as the Product Detail page.

I have added a product

When I click on View Detail for the product I am taken to the Product Detail page, but nothing shows up.  In the url field I get the following error -

http://localhost:4123/MiTek/Default.aspx?tabid=87&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0

What's up - any help would be appreciated!
