I'm new to zen cart and I have been trying for the best part of the day to get the tax to display on the checkout page. At the moment it just displays:-

Sub-Total: $70.00NZD

Free Shipping: $0.00NZD

Sales Tax: $0.00NZD

Total: $79.00NZD

I have read all the information on the tutorial pages and on these forums about this problem with no luck. I know that im probably making a stupid mistake but could someone tell me where im going wrong. Here are my current settings related to the tax calculation:-
