Hey Jeff, The problem is that the code in that blog post is not amenable to copy/paste. The ellipses are standing in for other parts of the code they are leaving out. The exception you're seeing is basically saying that the symbol "..." cannot be treated like an indexed collection. The syntax for definterface expects a body of lists that spell out the method prototypes for that interface.
