tonny Curtain Guru Från Netherlands Medlem sedan dec. 2016 tonny 24 sep. 2019 10:59 When I add the weight in kg like 10.00 it works fine but when I put it in as 0.025 in kg this is not accepted in the shippingmodule and also tryed to set all in gramm but does not work. In shippingmodule just enter a 0 for start instead of 0.25 so this is correct 0:0.8182;0.5:6.5702;15:9.0496;20:12.3554 Ok now I have it..You have to give in the Default Item (weight) in stock.... and let it be a bit lower then the option. The 0.025 kg will be rounded up to 0.03 kg in the cart.
