Viewing a entity

Hi

I am in the process of writing a cafepress module for DR7 and the first part is under review. I now want to extend this module and get the viewing under control. I would like to view the information in the same way as you view a node like www.example.com/cafepress/1. The entity "CPI_PRODUCTS" is working okay and i have a database full of the correct information. I have a cpi_products_load and save function. I also have the permissions setting correct. But there must be something wrong in the code. The code block is large so i will copy in what i think is importation if you want to have the complet code let me know.

****the error I get is page does not exist. *****(added later)
