My client wanted two different UPS shipping options: one for Canada and one for the States. I duplicated the upsxml module (calling it upsxml_usa) and configured it for his US account, and that seemed to work fine. However, USA customers who choose UPS get stuck on step 1 of purchasing - hitting Continue just reloads the page.
I've done some forum reading and think it may be connected to zones - any suggestions? Thanks.
