Yes, that was a hint. Just put the key where I have What Goes Here. You have to use the KEY to get the VALUE in return

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

Do you mean something like:

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

Oh, you are doing a challenge. I thought you were trying to write different code as a matter of practice. Which challenge is that? It is not listed that you are asking a question for a particular challenge.

Sorry about that. I found your challenge. You just need to do the assignment.

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

let ukCurrency = currencies[WHAT GOES HERE?]
