Anyone use these 2 together. I am having trouble understanding how to set up the cart.
When you click checkout, it opens up a page with the cart contents and a table with the choose of shipping method, zip code entry and state. The clicking next takes you a page with the cart contents, a table with the cost + shipping (via ups, usps, etc...), then a confirmation table with the the shipping method, zip, and state passed for the previous page.
Now, clicking secure order goes to 2CO and I get an invalid parameters error. I have read the removal of the $ will fix this error, but it doesn't.
My question, how do I get these 2 systems to play nice. I would think that the form that gets passed to 2CO would have a name, address, etc... I have made that form with the parameters that I have read it was supposed to have, but I get the same error.
If anyone has these, please let me know what you did to get it working.

Thanks
