JavaScript Function: I can't get pass Task 2 of 2. It keeps saying I'm not storing the "echo" variable.

function returnValue(food){ return food; var echo = returnValue( 'My argument' + food); } returnValue(salad);

script.js 
function returnValue(food){
  return food;
var echo = returnValue('My argument' + food);
return echo;
  }
returnValue();

Let take a look at your code

function returnValue(food){
  return food;
var echo = returnValue('My argument' + food);//  'my argument' is food that you passed on  to the function. Therefore, the is no need to call it twice.
return echo; 
  }
returnValue();

it should be like this

function returnValue(food){
  return food;
  }
var echo = returnValue('My argument' );// this is storing  the returnValue() into the echo var

So, there are a couple things here. You're calling returnValue() within the declaration of the returnValue() function. You can't do that. Also, in a function, you can only have one return statement.

If the end goal is to have the function return "My argument salad", try this:

function returnValue(food) {
  var echo = "My argument " + food;
  return echo;
}

returnValue("salad");

Thank you for your help. That didn't help. I think something is wrong with the app that checks for the answer.

While there is nothing wrong with using echo as a variable in JavaScript and they may require it in the challenge, I would not make a habit of it. Echo is a key word in PHP. It took me a second to realize that was not an error in JavaScript.
