Hi Brian,

You are so close! Try re-reading the question.

After your newly created returnValue function, create a new variable named echo. Set the value of echo to be the results from calling the returnValue function. When you call the returnValue function, make sure to pass in any string you'd like for the parameter.

It states AFTER your newly created returnValue function.

This means its looking for you to create your echo variable outside the function.

function returnValue(length){
  return length;
}

var echo = returnValue('test string');

The function you create in task 1 should remain as-is for task 2. The task 2 code will be added after the function and not inside it.

You just need to create and assign the "echo" variable by calling your function. So task 2 can be a one-liner.

I'll bet you can do it now without a code spoiler.

Hey Brian! The challenge asks you to create a variable (echo) in the global scope AFTER the returnValue function. var echo should equal the returned value of the function:

function returnValue(length){
  return  length;
}
var echo = returnValue('50');
