Oscommerce: Problem with Google Checkout v1.4.5_CCS

[pete2007]

I have installed the Google Checkout v1.4.5_CCS module to my
Oscommerce site but I'm having problems setting it up inside my Osc
admin section.


My problem is that once on the shopping_cart.php I click on the Google
Checkout image it basically redirects me to the same
"shopping_cart.php" page, surely it should be taking me to the Google
Checkout page. Does anyone know if I have missed out on something?


I have tried lots of different settings but I can't seem to find the
right ones.

Any help or advice would be most appreiated!
