Paypal Payment not passing phone number
I'm using eCart 5.0.3 to manage a simple ecommerce website for a client and payments are working as expected, but the delivery telephone number is not being passed to PayPal.
I've taken a look at the code but can't see anything obvious, and digging through PayPal's documentation is a bit of a needle in a haystack situation.
I've attached the checkout and confirm files to see if anyone could shed any light on the problem.
Thanks in advance for any help :0)
