AbleCommerce Shopping Cart Software

After setting up google checkout, I keep getting this:

Google Checkout Failed.
Google Checkout Response.IsGood = False
Google Checkout Error Message = Error parsing XML; message from parser is: Invalid value for attribute currency in checkout-shopping-cart/shopping-cart/items/item/unit-price:

Anyone else with this issue?

What is your Build Version and what is your basic currency?

Okay, the USD iso was missing. It goes to the google checkout now.

But i guess this doesn't work when you have different products assigned to different warehouse (shipping method)???
I did a test with 2 products that ship from different warehouses, both of which have their own shipping method. Google checkout put all my shipping methods in the drop down, and only allowed one shipping method to be selected.
