Hi Sean! You're right with using a append - just a couple of things - you need to append the value to the lists. Also, make sure european is spelt correctly otherwise the task will fail :).

Hope thats helps - let me know if you have any questions :)

You just assign the value from the key/value pair and put it in the parentheses. I have put an example below:

switch key {
      case "BEL", "LIE", "BGR": europeanCapitals.append(value)
      case "IND", "VNM": asianCapitals.append(value)
      default: otherCapitals.append(value)
    }

let me know if you have any questions :)
