Okay, that makes a little more sense. As far as the two configure files go... the one in my admin is slightly different than the one in my includes... and I'm not sure that I've got the settings right.

Does it matter if I put the www in there?

In my admin/includes/configure.php file I've got this:
define('HTTP_SERVER', 'http://www.eaglerockbooks.com');
define('HTTPS_SERVER', 'https://eaglerockbooks.com');
define('HTTP_CATALOG_SERVER', 'http://www.eaglerockbooks.com');
define('HTTPS_CATALOG_SERVER', 'https://eaglerockbooks.com');

// Use secure webserver for catalog module and/or admin areas?
define('ENABLE_SSL_CATALOG', 'true');
define('ENABLE_SSL_ADMIN', 'true');
In my includes/configure.php file I've got this:
// Define the webserver and path parameters
// HTTP_SERVER is your Main webserver: eg-http://www.your_domain.com
// HTTPS_SERVER is your Secure webserver: eg-https://www.your_domain.com
define('HTTP_SERVER', 'http://www.eaglerockbooks.com');
define('HTTPS_SERVER', 'https://eaglerockbooks.com');

// Use secure webserver for checkout procedure?
define('ENABLE_SSL', 'true');
If anyone could give me feedback on this, it would be wonderful...

Lastly, in my google checkout admin settings I've got the callback set to this:
And the Callback contents set to Notification as XML

(not sure if it was supposed to be XML or HTML?)

Thank you for your help, anyone...
