HTML block invalid


Why am I getting an error when I enter the html for my paypal cart button? It works on one landing page, but not the other. I am getting the error: “This html block is invalid and may result in a broken published page”…AND, it does not work when I try to add to my paypal cart for purchase. Paypal suggests the customer to go to the merchant’s website to address the issue…
