I am upgrading my cart from 6.15 by way of 6.2 to 6.41. In 6.41 admin My product data.. ie catagories subcatagories and the products and information shows up... In the shopping cart the customers see, the main catagories will show up but will not click thru to the sub catagories and products. Is there something simple I am missing?? (this works on the 6.2)

thank you,
Ron Gray
