207704 Oscommerce shipping mod

Currently I have a heavily modified oScommerce store at www. whole sale army surplus. This is a shipping mod needed. My domestic works great with a ups module, however Im recieving ups xml error reports I dont understand like "UPSXML TimeInTransit Error: 270014: Invalid Shipment Contents Currency experienced by customer with id 75 on 2008-03-15 11:47:04" and want to fix that problem. I want to use a table rate by weight to europe and canada, but it must work with my google checkout and paypal. I tried to turn on the table rate shipping but then my google checkout wont work. In short, explain and fix ups xml errors I recieve, create a table rate shipping according to international country, such as europe, austrailia, or Canada. Everything must work flawless as it does now with google checkout and paypal.
