storing return value

I need help with this code, I really don't understand why it wont pass. I rewatched the supporting video several times and am just not getting it. It keep saying "it doesn't look like you are storing the return variable." Thanks!

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

returnValue('30');

script.js 
function returnValue(width) {
  var echo = width;
  return echo;
}
returnValue('30');

Hi,

I think you just got a little mixed up from the way the question is worded.

The function needs to simply return its argument...

function returnValue(val) {
  return val;
}

After that you need to store an argument passed to the function in a variable named "echo"...

var echo = returnValue("My argument");

All together you should have this...

function returnValue(val) {
  return val;
}

var echo = returnValue("My argument");

Hope this helps :)
