I have to add 2 taxes to the prices calculation.
The first tax is based on the volume of the product in liters
The second are based on the weight of the packing of the product in kg
I’ll set up 2 attributes in product catalog, 1 for the litters and 2 weight of packing.
My plan is to set up 2 tax classes one for each of the attributes but how do I get Magento to do the calculating of those 2 fields and not the price.
The calculation also need to be € X Litter or € x KG, not a percent of a price.
Or do anyone know any extension how can do the trick.
