Purchase Options Using Paypal Extension

["smartlikestick" <webforumsuser@xxxxxxxxxxxxxx>]

Hi Y'all.

 I'm developing a tiny little E-Commerce site for my buddy to sell shirts for 
his band using Dreamweaver and the Paypal extension.  As they're shirts, I want 
the users to have to select a size, and have this information sent along with 
the payment confirmation.  Is this possible using only the paypal plugin?  
Alternatively, I'm able to fumble my way through JavaScript and or PHP if 
needed.  Looking for any insight I can get.

 Thanks
 Mike
