Order Data/Transaction Data not being transferred to PayPal

I need help from you smart guys, getting my order details to post in PayPal, and in particular on the shipping label information when we go to print. Right now I receive payments from my OpenCart site and we get the shipping address transferred but nothing about the order, such as Product ordered, Quanity ordered, Price paid, or discount information, etc. Our warehouse needs this to complete the order. Is there a way to get this information sent to PayPal Pro, to our account? Thanks, ChinaMot

In 1.4.9, paypal standard passes all these details by default. In 1.4.8 there is a paypal improved mod that does the same
pp pro may need to have the itemized details added

Thank you for your help and for getting back to me so quickly! Has this been a problem for others as well? I believe we are using version 1.4.8 and have had to make a number of changes. Is it fair to say that we will loose all of our modifications if we upgrade to the new 1.4.9?
