Hi haydensteed,

The second task is simply asking for you to get and assign the value of UK to a new constant called ukCurrency which we can do by using the following code.

let ukCurrency = currencies["UK"]

If this is at all confusing I recommend you go back and watch the previous video as Amit does show has you can access values for a given key.
