CiviMember gives me this error in testdrive when I click the PayPal icon to check out:
Payment Processor Error message:
10400:Transaction refused because of an invalid argument. See additional error messages for details. Order total is missing.
I followed instructions from
CRM-66 and followed the tutorial it directed. I was orginally getting a similar huge error message as CRM-66 was describing, and then after setting errors to be written to the log I get the above message.
