I have a standard credit card form that I need to integrate into Paypal API . I've tried the Paypal API samples HERE and I can't seem to get them to even work. Honestly, they seem way too distracting and overly complicated to be called "samples".

Anyone have a simple example that uses a simple form in an aspx page?   Thanks.

Which PayPal method are you looking to use?

if you are using payflow pro then Rick Strahl has a nice tutorial on how to use it.
