You need to define echo outside of the function, not inside it. 

var echo = returnValue('apple');

I'm a bit confused by your question, but from the looks of it, you are looking to do this:

function returnValue(number) {
  return number;
}
returnValue(1);

This should return 1 as your number. Is this what you were attempting?

Double-check the prompt and see my answer -- it wants you to define echo AFTER the function, not before it.
