Its suppose to show the balance of my paypal income. Anyone already got this? thanks! i had the same problem, and found this article with no replies while searching for a solution. i thought i would post my resolution for others. first of all make sure there are no leading or trailing spaces. to resolve my issue i deleted the API in paypal and created a new one. carefully entered the credentials and it worked fine from this point on.
