PayPal Advanced passing shipping address but not ship to name

I am starting a different thread here because this is a different issue in the same setup I posted earlier (found here http://www.webassist.com/forums/post/208901/)

This one has to do with shipping addresses. My client pointed out that when he logs into paypal.com the "Print Shipping Labels" button is missing for all transactions that were done using a credit card on the website. In other words, they don't log into PP, they just use their cc.

We have been back and forth with PayPal about this and once they even admitted that they were aware of the problem and they were fixing it. However, now they say I am not passing the information correctly. They won't tell me what or why, which is odd.

When I log into the manager.paypal.com account, I see both the billing and shipping addresses in the transaction details. However, I did notice that the customer's name is only showing up with the billing address. The shipping address is missing the person's name. The address is there, but no name. When reading the docs, it doesn't mention anything about this. It simply says...
"Note: If you pass in any of the ship-to address parameters such as SHIPTOCITY or SHIPTOSTATE, you must pass in the complete set (that is, SHIPTOSTREET, SHIPTOCITY, SHIPTOSTATE, SHIPTOCOUNTRY, and SHIPTOZIP)."

I do know that the name is being passed as FIRSTNAME and LASTNAME but I do not find anything like SHIPTOFIRSTNAME. Is this suppose to be there? Am I missing a variable?

It seems like I am missing something because I have both a billing and shipping form and the shipping form includes the field "First_Name_2" and "Last_Name_2". The billing form uses "First_Name" and "Last_Name".

All of the address information, SHIPTOSTREET, SHIPTOCITY, SHIPTOSTATE, SHIPTOCOUNTRY, and SHIPTOZIP, is included but I don't see anything for the ship to name. Where should I be looking?

Any thoughts?

Thanks,
