Look at the method that contains the reference.  If it's marked by 
"static" in the type declaration (basically, where the return type is 
defined), then it's more of a procedure call than something 
associated with a particular object.  Static methods don't have a 
"this" pointer, and can't directly reference variables within objects 
(there are exceptions, which are conceptually somewhat clean but not 
really relevant here).

To put it another way, everything that a static method references 
directly must also be declared as static.

Might be better to define a small internal class that keeps the two 
items, and then have an array of those.  That idiom makes it much 
easier to ensure things stay synchronized. But that's not the issue 
that's causing the error message.
