Shipping variable not working in Standard Payment process
I am trying to submit a form via standard process to Paypal and have them display the shipping cost as I pass it. I am using the _cart/upload option since I have my own shopping cart build. Everything works fine except Paypal is ignoring my shipping cost. Why is it not working? The options for shipping calculations provided by Paypal are a bit too basic and don't fit my needs. Any kind of help would be very appreciated.
