Getting an error from addChoiceWith

I keep getting an error in this section:

func addChoiceWith (title: String, story: Story) -> page { let page = page(story: story) return addChoiceWith(title: title, page: page) }

The part that says:

let page = page(story: story)

Keeps coming up as an error. It says that "Variable used within its own initial value".

Does anyone know what is going on?

Thanks

Yep, you need to call it on the type, not the variable. Should be: let page = Page(story: story)
