... instead if I setup max weight to 30Kg (in configuration), the zone shipping module work fine because show me:
Total Items: 2 Weight: 60Kg Amount: €564,00
Express courier (Shipping to FR (3 x 22.00Kg)) €86,40
I'm an italian merchant: my courier have rate for Italy different from Europe, so max weight for Italy is 100Kg, instead max weight for Europe is 31,5Kg.
The solution, I think, is to have two max weight (or more) for different country.
