PayPal Donation using CCK

I know a few non-profit's that might want to give this tutorial a spin. This how to example features a custom CCK donation form that dynamically generates the PayPal button once the donation parameters are submitted. The user then simply clicks the button and is off to PayPal to pay for the donation. It is assumed that the reader is familiar with the PayPal developer's requirements to process payments. It is also assumed that the reader is familiar with CCK and computed fields.
