I have made different Shopper Groups and created some Calculation Rules but they are not applying to a shop pen in that group when they are logged in.
eg. I have:
Backend - Shopper Group: Trade 1
Backend - Calculation Rule: Trade 1 = -10% and selected the product categories
Fronted - Registered using the VirtueMart registration.
Fronted - Confirm the registration and log in
Backend - Added the shopper to the Trade 1 Shopper Group
Fronted - Go to a product in the categories that has the Calculation rule
But, the price is the normal price not the Trade 1 price
This is the site I am working on: http://carlneumann.com/sink/
Go back to your tax - It sound correct what you have done -
Check that the Tax is not only visible but Published.
Check the - "tax per product" - maybe just add them all to start as a test -
