After running the site I can see TBH only has 2 levels for the product. Department and product. The customer can only have 2 levels
examlpe:
level 1- and product

He can not have level 1 - level 2- and product.

this is a must in web-shops today.
So has anyone done this to there TBH site.

Or does anyone know how to go about making this possible in the TBH site. ??

I think that you, and others, are forgetting that this site is constructed to be a fully operational site meant for [u]learning</u> ASP.Net 2.0. That means it will have some quirks and other miscellaneous problems. [u]It is not an out of the box site with everything operational and configurable.</u> You can do whatever you like to enhance the site, but you've got to take the time to read the book and examine the code. Better yet, don't just copy the site, use the concepts taught and create your own site!
