Display the contents of the PayPal Shopping Cart to the
buyer. This variable must be set as follows:

The alternative is the add="1" variable, which adds an item
to the PayPal Shopping Cart.
If both add and display are specified, display takes
precedence.
1
handling_ cart Optional Single handling fee charged cart-wide. If handling_cart
is used in multiple Add to Cart buttons, the
handling_cart value of the first item is used.
item_name_
x Required The name associated with item x. To pass an aggregate name
for the entire cart, use item_name_1.
Applies only to the Cart Upload command.
paymentaction Optional Indicates whether the payment is a final sale or an
authorization for a final sale, to be captured later.
Allowable values are:
 sale
 authorization
 order
The default value is sale. Set the value to authorization
to place a hold on the PayPal account for the authorized
amount. Set the value to order to authorize the payment
without placing a hold on the PayPal account.
IMPORTANT: If you set paymentaction to order, use
the Authorization & Capture API to
authorize and capture the payment
payments. The Merchant Services on the
PayPal website let you capture payments
only for authorizations, not for orders.
shopping_url Optional The URL of the page on the merchant website that buyers go
to when they click the Continue Shopping button on the
PayPal Shopping Cart page.
For more information, see “Sample HTML Code for Add to
Cart Buttons that Continue Shopping on the Current
