Can't figure out why I am not getting this code right, can anyone help? I am suppose to assign value for key to constant

I believe I have the code correct but it is not passing me through. It keeps giving errors. Has anyone had this same problem? Any help would be great, thanks in advance.

dictionaries.swift 
let currencies = ["US": "Dollar", "UK": "Pound", "JP": "Yen"]
let ukCurrency = currencies.removeValueForKey("UK")

Just like you said. When retrieving a value from a dictionary, use this example: ``` let greeting: String = ["Hello": "Formal", "Hey": "Irrformal"] let formal: String = greeting["hello"]
