I'm a bit stuck on the second task of this quiz. I could use a little help.

I've re-watch the video previous to this quiz and am still having trouble understanding what I'm supposed to say for the second task in this quiz.

Provide some code that you've tried, so we can see what you're doing wrong.

It wants you to assign the value at currencies["UK"] to a constant named ukCurrency; not assign currencies["UK"] to the value "ukCurrency". Meaning: 

    let ukCurrency = currencies["UK"]

Not: 

    let currencies["UK"] = "ukCurrency"

here's the question: Challenge task 2 of 2 Assign the value for key "UK" to a constant named ukCurrency.

here's what I've placed:

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

Could I have you rephrase that a bit? I'm having trouble following.
