authorize.net transaction cannot be accepted

I am having problems connecting with Authorize.net. I am attaching the checkout.php, and confirm.php. When I submit the checkout page I am sent directly to checkout_failure.php. I contacted authorize.net and they are not seeing any attempted transactions. they also said the credentials I have are valid. site is www.cutestpetcontest.com. I am working with PowerStore 3 and I am not in "test mode". see pm for ftp access.

What is the URL to the web site? I'll need that to test.

www.cutestpetcontest.com

It appears you had edited the authorize.net server behavior with eCart 6 and the code was out of sync. It started referring to the settings in your webassist/ecart/checkout/credentials/gateways.php file, but that file wasn't added to the confirm.php page.

I fixed it by adding a require_once to the confirm.php page to include the gateway settings definition.

Thank you for going the extra mile!

It looks like the cart fields are not being mapped to the Authorize.net fields properly. If I use the WA server behavior tools I will likely run into another version problem, unless I am wrong about that. What file should I work with to fix the mapping issue?

You shouldn't run into problems updating the Store Cart Details in database server behavior to the new version, it hasn't changed as much as the checkout process, so the new code will work in this context.

The data being passed to Authorize.net is not mapped correctly. How do I see where the values are coming from and/or how to map the fields from the cart to Authorize.net correctly?

I was able to fix this. This thread can be closed.
