Hi Michael,

The question for task 2 is as follows.

Assign the value for key "UK" to a constant named ukCurrency.

What this is saying is you need to assign the value for the key UK to a new constant called ukCurrency, to get the value for a dictionary key as explained in the video we use the constant currencies along with the square brackets notation and a string containing the key name.

let ukCurrency = currencies["UK"]

Happy coding!
