Hi Will,

you forgot the closing square bracket at the end of your dictionary and you where asked to only assign the value for key "UK" to a constant named ukCurrency like this:

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

Hello, there is no comma after "Yen". You may try the following: let currencies = [ "US":"Dollar", "UK":"Pound", "JP":"Yen", let ukCurrency["UK"] = "United Kingdom" ]

Hope it helps
