Problems implimenting checkout using checkout wizard
I have a couple issues, but rather than post multiple threads I'll just put them here.
I've used the checkout wizard to build my checkout pages, and am using USPS for shipping, Protx for payment and included the paypal payment option.
1. When choosing the paypal payment option, I get the following error:
I'm pretty sure the error is something to do with the USPS servers, and this error shows up whether a zipcode was entered or not.
2. When using the standard checkout button, I was able to clear up a previous error I was getting by switching my USPS account over to production servers. But when viewing the confirmation page the only shipping charges that are being calculated are from the initial "rate per item" that I had set during the ecart wizard. It seems the pages aren't fetching shipping costs, however there is no error.
3. There doesn't seem to be anywhere in any of the pages generated by ecart for customers to provide payment information, only a billing address. I ran through the wizard more than once (selecting both the "remote" and "notify" methods for Protx) to see if I missed anything but there doesn't seem to be any pages built to collect credit card info. What exactly am I missing here?
* I'm also having a problem finding, inside the extension, where to go to make any changes to shipping or payment settings after the fact. Does that mean that once the pages are generated that you have to sift through the code to make any changes?
