When I calculate, Cape Pack is giving me the following error: "Net Weight is > Gross Weight".
In Cape Pack, your Gross weight is the entire package weight including the contents and the packaging. The Net weight is just the contents of the package. They can be the same, but you can never have a Net weight that is heavier than the Gross weight. When you do, the program will stop and make you correct it. Correct your weights and recalculate.
