The challenge is asking you to retrieve the value for the key "UK" and assign that to a constant named ukCurrency. Your line of code creates a second dictionary and assigns it to ukCurrency.

The answer is:

let ukCurrency = currencies["UK"]

Thank a lot, i was really stuck on that one. The video didn't explain much about this. but i really appreciate it
