Google Checkout module for ZC 1.3.x (beta)

[mutabor]

Hi !
I installed Google Checkout module for Zen Cart and Created sandbox account and have some troubles..
It seems to Google Checkout module not working!!
Could U explain how that module should work
There are 4 steps for creating order:


index.php?main_page=shopping_cart – shopping cart. I inserted code
// ** GOOGLE CHECKOUT **
<?php include(DIR_WS_MODULES . 'show_google_components.php'); ?>
// ** END GOOGLE CHECKOUT **
But it will work only when My shopping cart is empty. Then i push the button go to checkout.
And redirect to the page
index.php?main_page=checkout_shipping - type shipping info. Then push continue.




index.php?main_page=checkout_payment . Inserted the code


// ** GOOGLE CHECKOUT **
if($selection[$i]['id'] == "googlecheckout")
continue;
// ** END GOOGLE CHECKOUT **


And I should select a payment method. I activate only google checkout and Check\money modules at the admin part. So i see only Check/Money Order payment method at that page. Where google checkout? Should i activate any more modules for working with google checkout? How it work?
When Google Checkout module send data to the Google Checkout Account? How I could check It ? Thank You so much for Your answerers.

It seems I have the same problem. Please advice
