Hello,
I am new to this module and to programming in general.

I fixed most of my problems, one of them was that "googlecheckout" payment module name in ZenCart is "GoogleCheckout" not "googlecheckout", so look out for that.

I am having a problem right now with the most important thing. When a customer selects Googlecheckout (GCO), and confirms the purchase, the customer is automatically routed to the checkout_success page and doesn't even go through the google checkout. The customer doesn't even get a chance to pay, and becomes a paid customer in zencart.

Where have I gone wrong? I didn't change anything except for what was mentioned at top. I am using production with correct IDs

Oh by the way, if the customer clicks on the googlecheckout icon, everything goes through perfect. But when the customers chooses the radio button in the checkout screen, that's where the problem happens.

HELP
