Guys,

Our outgoing messages to GCO are not the issue. They're fine and you're probably getting an email from GCO that you have an order.

The problem is the XML messages coming back from Google to your ZC.
For one of many reasons, the googlecheckout/responsehandler.php may not find those messages to be processable.

I'm not going to speculate as to the reason your's doesn't work.
But, if so, ZC will not know anything about the order or the customer.

If the customer does not have an account, your ZC will create one using the customer information sent back in the XML messages from google.
But not if the responsehandler doesn't like it for some reasons.

See the googlecheckout/response_message.log, not the error log.
There is where you should find the XML that arrived from google, they are not error messages, they are the business data your cart needs to create an account and process the order.

Thanks for pointing out that they are probably hitting checkout in the header menu. I suspected that, and that would explain why I'm seeing so many hits to checkout in my Google Analytics, but no sales.

I too have a only the Google checkout button on my shopping cart page, and probably should disable the checkout button in the header menu.

Good luck!!
