I don't understand step 2 of this question. Where should I put the variable "echo"?

Here is the code I used:

function returnValue(number) { var value = number; return value; }

returnValue(3); var echo = returnValue();

script.js 
function returnValue(number) {
  var value =  number;
  return value;
}

returnValue(3);
var echo = returnValue();

You have it in the right place, but you forgot to pass an argument to your function when you called it.

The line that calls the function but doesn't assign or otherwise use the returned value is not needed and can be removed.
