Error Tracking on PP_Express failure?

I was trying to add checkout response error codes to the failure page on a pp checkout, but there are no bindings on that page which tell me why the express checkout is failing... Is there any way to track these failures?

Go to the bindings tab and click the plus button and go to eCart->Local Checkout Response... you can add all three stages of the express checkout process... all of which will have bindings you can drag on the page to help diagnose errors.

I'll give you a hint.. if you haven't changed anything.. it is your username, password, or security key is incorrect. The wizard almost always does the rest right for you.

On the pp_checkout_failure page.... there is no local checkout action available for the express action. I could add a local checkout for direct Paypal payment, but is that really going to tell me anything?

Anyway, it is working now... just for future reference... I'd like to know the proper procedure..

The local checkout bindings are there in the list.

They are:
"Authorization for Express Checkout"
and
"Payments for Express Checkout"

depending on whether you get the error on the checkout page before going to paypal or when you get back and are trying to finalize the transaction.
