Hi Ikjap Singh,

You have the correct code for this challenge, however, it's in the wrong place and you have more code than you need.

  1. Your ukCurrency constant should be referencing the value for the key UK
  2. currencies["UK"] shouldn't be trying to assign a new value as constants can't be changed
let currencies = [ "US" : "Dollar" , "UK" : "Pound" , "JP" : "Yen" ]
let ukCurrency = currencies["UK"]

Happy coding!

Thanks for helping me out
