Add SKU number to Paypal details
I already have a Product Id, Size, and Color showing up in my Paypal details. I want to add a SKU number to show also. I have it attached to the cart and it is displaying on the shopping cart page correctly. What code and where do I add it to make it show up in the Paypal details?
<?php $SKU = $siteCart->DisplayInfo("SKU"); ?>
