Hi Kenneth,

You have the correct answer in your println statement, however, you've added a string before it which isn't required. The challenge is simply asking for you to print the count for todo which we can do using the below.

println(todo.count)

Happy coding!

You are printing "Items on todo list: \n todo.count"

the variable todo needs to be outside the " ". You dont need to display the message and your variable is not really a variable inside " ", it's just a string. the correct answer would be

println( todo.count)
