Shipping range problem

[brad]

I've put a weigh range on my prestashop shipping its like this

0-1 kg 10$
1-2 kg 20$

when its on 1kg it chooses the most expensive one, how can i change that? thanks

There is no option in PrestaShop to select the lowest range. The easiest way would be to use ranges like the following:

0-0.999 kg $10
0.999-1.999 kg $20

Increase the number of 9s depending on the number of decimal points used in your weights.
