UK Postage with Powerstore 3

Thank Eric that's great and makes alot of sense. I've followed your instructions exactly and created a new rule called post and pack. I uploaded the entire WA-eCart directory and tested the site, but when I added a product to the shopping cart, shipping still didn't appear on the cart page. I've attached a screen grab of the settings I used for the post and pack rule in eCart, the cart page, but also the Powerstore Admin settings page. Have I got the shipping settings correct in Powerstore, or do I need to modify something there? I've attached the WA-Globals file aswell in case there's something wrong here.

Thanks for your patience on this I just don't know what I'm doing wrong.

Neil
