handling paypal response errors

[Tom von Schwerdtner]

I'm unclear on how to handle paypal response errors,or more to the point, I'm unclear on how to access them.

It seems the convention is to setup th epaypal arguments in a view, and then end with:

kw = {...}

pp = PayPalPro(**kw)

return ppp(request)

So where/how do I access any response errors?  Or am I going about this all wrong?
