united kingdom zone rates for couriers not calculating shipping correctly

Would appreciate a little help, if anyone can point me in the right direction. I have no hair anyway, but it would have been torn out with this problem if i had!

I am using the UK zone rates for couriers shipping method, and have this set for my rates.
28:10.00, 50:16.50, 75:24.75, 100:33.00

soon as i go on the shop and go over 28kg, it is setting the delivery cost to £20. If go to 60kg it sets the rate at £30, blatantly ignoring what i am telling it to do!

I have tried installing the table rate with the same values for weight / shipping and that does the same thing?

Any ideas anyone?

What are your settings in the zone rate module?

Go to your Configuration ... Shipping/Packaging ... and change the Mximum Weight to 5000 and then go to the two Tare Rates and set to 0:0 ...

Now see if this works correctly for you ...

Ajeh, you are a star. thankyou!

Thanks for the update that this resolved your shipping issues on the cost for the Zone Rate zones ... :smile:
