Why doesn't i get any error, but at the same time a bummer?

What have i done wrong in this test? I don't get any error, but i do not pass this challenge.

dictionaries.swift 
let currencies = ["US": "Dollar", "UK": "Pound", "JP": "Yen"]
let ukCurrency = ["UK"]

Hi Adam,

You need to access the currencies dictionary with the "UK" key. That looks like:

let ukCurrency = currencies["UK"]

You can access the currencies dictionary by providing a key; this will return the value associated with that key. You can then assign that returned value to your constant, ukCurrency.

I hope that makes sense.

Steve.
