Google Checkout module for ZC 1.3.x (beta)

[BlessIsaacola]

I'm using Zen Cart 1.3.8a with the Google checkout module - the GC button shows in my cart, but it doesn't appear as a payment option when a user goes through the registration process. Is there any work around for this? I really want my customers to register before paying.

You might want to read Google Checkout policy as you're missing the point of offering GCO. They don't want you to force customers to register. Both PayPal Express Checkout and GCO exists for convenience for the customer to checkout without creating an account or login on the site offering them.
