Have the rare sale where I have to pack/ship a box larger than the usual 4 x 4 x 4 (in) I normally do.
These are the dimensions I entered.

Minimum 14 x 9 x 0.1cm. Maximum weight 2kg, length 60cm and sum of three dimensions 90cm
This is the message I get when I try printing a label. (Canada Post Tracked Packet USA)

.
The "purchase shipping label" is grayed out.
What am I missing here? Thanks much.
