Two of the sites want to have a PC Configurator (so they can sell custom computers)... Looks like it would be best done in Interchange, instead of Agora...

However, I'm having trouble working with the options, and the Interchange site is no help...

Anyone have a quick guide/tutorial on how to get that going?

Thanks

Sorry, don't use Interchange, but I know osCommerce has a mod specially just for this:
