The term enum (AFAIK) is comes from an old C++ hack, where you'd 
create an actual enum to represent variable that's useable 
compile-time.

Anyways, when you declare an actual enumerate, you have to 
declare:
1) The enum type
2) The enum values
3) The enum variable

So in your case, it would have to be:
--------
enum Enumerate
{
    state1 = 10,
    state2
}
Enumerate i = Enumerate.state1;
-----
