Why did I get the error "You have requested an outdated version of PayPal. This error often results from the use of bookmarks" in Outlook Wizard?

Issue
You received an error message saying that you requested an old version of PayPal.

Cause
This error happens only if you choose the Basic payment type when creating a button, because there is a space between "cmd" and "=" in the code.

Solution
Use one of the other payment types, such as Product, Service, eBay Auction, or Donation.
