The mystery is solved... at least for my cart.
When I signed up for 2CO the email they sent did not include an URL to use for the cart. However, on their Shopping Cart Specs page they instruct you to use the URL
https://www.2checkout.com/cgi-bin/sbuyers/cartpurchase.2c
This URL did not work with my cart! However, in reading over posts from milehightrader and extensive conversations with Dan, I have discovered that the URL suggested by milehightrader works. Here it is:
https://www.2checkout.com/cgi-bin/Abuyers/purchase.2c
So... in my hair-tearing struggle with the elusive wildebeast I can offer up the following suggestions.
First, in Store Manager, enter the correct URL which I have bolded above. In the "ready to go live" box enter yes (if you are ready to go live).
Then, on 2CO's admin pages, set up the following parameters:
In Account|Return, navigate to the third section on the page titled "cartpurchase.2c parameters". In this section set the option box to Yes and enter the full URL to your store ending with agora.cgi. So it will look like
http://www.yoursite.com/yourstoredirectory/agora.cgi
Now here's a bit of 2CO strangeness. When you do this, it also populates the Yes/No box and URL field on the page Shopping Cart|Cart Details.
You are almost there. Navigate to Account Details|Sales Details and make sure that "Put shopping cart in demo mode" is NO and "Request shipping address" is YES. I think the rest of the other parameters are optional as to how you want this service to work.
These "simple" setup parameters got my cart going after hours of head scratching. I am a complete newbie to scripting languages (heck, ask me how to do something in VB, VC++, or Fortran and I can whip it out in a matter of milleniums) so I apologize in advance for this being a "cookbook" approach to solving the problem. I'll probably send in a request for explanation to 2CO to find out what the difference is between their two scripts, but if it works, what the hey, let's make some money!
I hope this helps everyone who has been fighting to make 2CO work for your site. Thanks again to Dan for hours of his time helping me narrow down this problem.
Cheers and happy selling!
