Add item description to Express Checkout Custom Credit Button code

[BrianRay1]

I would like to add an item description to the Express Checkout Custom Credit Button code found here https://developer.paypal.com/demo/checkout/#/pattern/credit 

The button works, but there's no item description on the PayPal packing list or in the account summary.

Thanks for your time.
