This variable is not in the global scope.

A variable defined inside a function has a scope limited to that function, but the console only has access to items in the global scope. It's normally good practice to not place things in the global scope, but for debugging or experimentation you could declare the variable outside the function and then just assign it inside. Then you could access it from the console.
