I'm not sure why this isn't storing the result of the returnValue function into the echo variable..

JavaScript var returnValue = function(singleArgument) { return singleArgument; }

var echo = returnValue;

returnValue("14");

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

var echo = returnValue;

returnValue("14");
index.html 
<!DOCTYPE HTML>

You almost have it! In the second line you did not provide a value to the function (you did that in the third line). see below for the corrected code. 

var returnValue = function(singleArgument) {
  return singleArgument;
}

var echo = returnValue("14");
