I am facing some problem in Smith module (version: SmithCart04.02.00-DNN5)
 
Please check followign steps which I follow and I face problem:
1) I have created pages and set Product module and Category modules on page.
2) I added new tab called "Shop Admin Products" and I added new buy now module. System should allow me to add a category that is not shared with other catalog.
3) I should be able to add products that are not shared with other catalog products. We can enter new items for this catalog through the store admin tab.
4) After setting up new product - the system errors "object not set". And new added product is not diplay in that new category.

Can any have idea about this problem?
 

Thanks in Advance.
