Code error?

I'm editing a plugin, and i found a error, i deleted the MoveLog end; but i getted more errors, see:

(NO DELETION)

Error: MoveLog end; ( duplicate local variable )

Could you please post the stack trace.

 

What?put the Main? i dont speak english pretty good sorry
OBS: How i can put java codes?

 

GaaTavares
Java codes are in [ syntax=java][ /syntax] tags.
A stack trace is the error you get in console.

 

@Pink_Slime

Oh sorry, i get this "flood error" on console:
