CiviCRM Community Forums (archive)

I've been doing some contract Drupal work for a client who uses CiviContribute to process payments from their customers.  All of the credit card options seem to work fine, but the PayPal button (included in the form upon enabling the PayPal processor) always returns an error when clicked, whether or not the user has an existing PayPal account.

I've checked with PayPal and they believe that the "cart" is passing the wrong variable for the "SOLUTIONTYPE" ID, which apparently needs to be "mark" or "sole" depending on the preferred permissions for users without existing PayPal accounts.  The problem is, I cannot locate any files within the CiviCRM or CiviContribute packages that contain these variables or the "SOLUTIONTYPE" id.

Any help would be greatly appreciated, as I have already done fairly extensive research, ultimately yielding no results.  I am admittedly a N00B at CiviCRM.  I have included the entire error message below, albeit brief:

"---

Payment Processor Error message
: 10453:Transaction refused because of an invalid argument. See additional error messages for details. The Solution Type you requested is not supported.

---"

Thank you for the reply.  I have taken a look at that file (PayPalImpl.php) and I have located several instances of the "invokeAPI" function.  This seems to return the "$args" function, which uses a variable named "method" ...I was wondering if this could be related.  I have searched for the "solutiontype" function, or something similar, to no avail.  Is there something I'm missing?

Is there a location where the "mark" or "sole" variables are usually placed in the code for similar issues?
