We have zen cart 1.3.8a and we use paypal IPN - website payments standard.

Can anyone tell me where we can change variable no_shipping used in the shopping cart being posted to PayPal as

name="no_shipping" value="1"

to

name="no_shipping" value="2" ?

We want to make sure customer's shipping address was copied and transferred from zen cart orders to the paypal transactions so that once we get order, we login to our paypal account, and click "print shipping label" where customer's shipping address was already input

Thank you very much for your advise
