====== Paypal TroubleShooting ======

===== I get an "INVALID" message from Secure-eBook =====

Description:
The transaction works (you received confirmation from Paypal).
You are taken back to the Secure-eBook Web site and the following error is displayed:

  The transaction has failed.  Payment processor returned this message:
  
  INVALID

===== Solution =====

This message is returned when your Paypal's **Payment Data Transfer** (//PDT//) has not been turned on.

To turn on //PDT// please follow these steps:

  *Access "Website Payment Preferences" from your PayPal Account's Profile.
  *Set Auto Return to ON.
  *If the Return URL is empty, set it to your company or product's home page. If there already is something there, don't change it.
  *Set the Payment Data Transfert to ON.
  *Save your changes.

  *If this is the first time your turn on //PDT//, Paypal will show you your //Identity Token//.

  *Select the complete token and copy it.  (Under Windows, you can press both CTRL and C keys simulatenously to make your computer "remember" your selection).

  *If Paypal does not show your //Identity Token//, go back to the "Website Payment Preferences".  It will be displayed in the "Payment Data Transfer" section and you can copy it from there.

  *Log into your Secure-eBook account.
  *Click on "Payment Processor" under the "My Account" section.  Paypal should already be selected. 
  *Keep clicking on "Next" until you reach the **Paypal Account Configuration Identity Token** page.
  *Paste your Identity Token in the edit field.  (Under Windows, you can press both CTRL and V keys simulatenously to make your computer write a copy of your last "remembered" selection in the currently selected edit field).

  *Click on "Finished" to save your changes.
