Hi everybody!

I'm having a problem with Google Checkout.

I configed Merchant id and Merchant Key on my testing site and it worked correctly.

But when I configed the same Merchant ID and Merchant Key on my customer's site, I meet this error:

"Oops! ... has sent Google a shopping cart with errors in it. We'll contact them to ask that they fix this problem. As this could be a temporary issue, you can go back in your browser to try checking out again."

I met that error when I test on my testing site and I changed value of "GoogleCheckout Carrier Calculated Shipping" to false and it worked!

But it doesn't work with my customer's site.

May it because Merchant ID and Merchant Key are used for only 1 site???

Could you explain for me? Thanks alot!!!
