Orders API (apparently) Doesn't Return Button Pulldown Item

[TechCatTodd]

I am a newbie to PayPal API so forgive me if this is obvious or covered in FAQs or other documentation; I did search a bit.

I created a button (using the PayPal site and put the html form code on my web page) with a pulldown menu and price (1st screen cap).  Looking at the order on the PayPal site or in the email received shows the selected item (2nd screen cap). I got the PayPal Orders API working but nothing in the information returned shows the item selected and purchased. This is pretty much the main thing I need to access to perform the correct post purchase activities.  Do I need to tweak the html or get away from a pull down? Surely there is a simple way to get this via the API. Any help appreciated.
