Show Shipping Weight Total on Order Page

Hi,

I'm trying to get the shipping weight total to show up on the Orders page. I've made some adjustments to the code so that it shows the shipping name and address by adding:

esc_attr($meta["mp_shipping_info"][0]['name']) . '
' . esc_attr($meta["mp_shipping_info"][0]['address1'])

The last thing we need is to be able to see the total weight of all products. I've searched throughout most of the general arrays and couldn't find anything.

Any help would be greatly appreciated.
Thanks!
