Hi James, There are few issues with your code:

1) second line -> you are passing variable sayHi as an argument to alert method. You have already used this as a name for your function. You could pass any variable to alert method as long as you have defined this variable and this variable contained a value. In this challenge all you have to do is to pass a string to alert method. In this case string 'Hi'.

2) Now you need to call function - we call functions in javascript by using their name following parentheses - like this: sayHi(); Putting keyword in front of function call with produce error and you don't have to alert the whole function again as you are using alert method in your function already.

Check the code below and see the differences. Hope this helps.

function sayHi() {
  alert('Hi');
}

sayHi();
