Hi,

To put code into a forum post use triple back ticks -- ``` — around the code. I fixed your code here, but in the future here's a forum discussion that describes how to add HTML, CSS, JavaScript or other code to the forum: https://teamtreehouse.com/forum/posting-code-to-the-forum

You've already created your function so then all you need to do it call it. As below:

// here is your function used to pass the first challenge
function returnValue(max) {
  var echo = max;
  return echo;
}

// then you call it and assign it to the variable
var echo = returnValue('abc');

Just try it again I updated the code a few seconds ago and wonder if you happened to try it while I changed it.

I left the closing brace in the wrong place.

Hi Durul

You have to return the argument that is passed into the function, in your case max not set the variable echo to the string 'My argument'.

Your code should be as below

function returnValue(max) {
  var echo = max;
  return echo;
}

Hope it helps!

You have to call the function outside of the braces, passing 'My argument' to it. Basically it asks you to this.

function returnValue(n){
  return n; // you should use a more descriptive argument in general though
  }

var echo = returnValue('My argument');

the question is Now that you've created the returnValue function, call it, by passing it a literal string value -- a series of characters in quote marks like this: 'My argument'. Store the results of the function in a variable named echo.

but my code is not still working

I could not take green light.

So the method for calling a function is to type the function name followed by the argument you want to pass into it in parenthesis.

And then to complete the challenge you need to pass this back into a variable named echo such as below:

var echo = returnValue('abc')

function returnValue(max) { var echo = returnValue('abc') return echo; }
