Zones Table Rate Shipping Module

[maxidvd]

I have 1 zone for each state in Australia - but need two prices for each state. Registered Mail or Express Post so I simply copied the zonestable.php mod and renamed everything accordingly. (its works fine)

1. is priced for Express Post from: 0kg - 10kg
2. is priced for Registered Post from: 10kg - 20kg

The problem is when a customer in NSW has cart content of say 15kg, basically only Registered Post should be displayed but both mods are showing and the Express Post mod is displaying $0.00 for postage amount and it allows the customer to select it and check-out with free post??

I dont want to post Express Items any heavier then 10 kilo, thats when registered mail kicks in and takes over - how do I disable the Express Post ( ztexpresspost.php copied and renamed from zonestable.php) mod when the order is over 10kg?

I have maximum shipping weight set to 20 kg in configuration, Free shipping is also disabled.

Express Post = 0.5:10,1:15,2:17,10:20
Registered Post = 20:20

Express Post is supposed to stop showing or at least stop functioning if cart >10kg

And how do I get the Registered Post to only start displaying when the carts total weight exceeds >10kg?
