I am trying to create a tota weight property for the deal. Each product has a unit weight. I attempted to create a deal property that will add the unit weight of all products on the deal but it ignores quantity. Thus, if you a line item with a weigh of 50 lbs, that total weight field is going to show 50 lbs regardless of quantity.
If I could use a calcluation property (line item weight) on the product, I could take the unit weight times quantity, then change the total weight property on the property to sum the line item weights.
