$shipping_num_boxes Problem with custom shipping module

[Reesy]

Hello,
I have a question about $shipping_num_boxes please.
ermmmm
It may sound stupid but what does it do?
Is it refering to the number of items in a cart?

I attach a shipping module (class is named _) for the second biggest shipping company in Japan.

Im trying to config the cart to use these, and the problem Im getting is....
Add 1 widget 0.01 kg - shipping module seems to work and reports the correct shipping amount.

Add 10 widgets 0.1 kg, shipping module reports its too heavy/large.
Is there an admin setting I have missed somewhere?
Appreciate any help here.
Thanks in advance.


PS Ive gone through and done most of the fixes in the thread for 1.8a.
