Hi Barry,

As per the challenge currencies should be a constant which we can create using let instead of var and we also need to store the value for the key UK in another constant called ukCurrency.

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

Happy coding!

thanks Chris. Looks like I was following the example in the lesson too closely - we used a variable when creating the dictionary.
