I have no idea how to set "var echo" to the "returnValue"

I have been stuck on this challenge for a while now and I need some help. Step 2 is asking me to set the variable "echo" to the returned results from "returnValue". I honestly don't understand how all of this works. Could anyone elaborate on what's going on here? What am I missing?

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

returnValue('Jose');

Hi Jose Mendoza, you are really close on this one. only one thing to change, and that is the var echo needs to be out side of the function. and you need to call the function as well. like so 

var echo = returnValue("Jose");

what is happing here is you are taking the return value of the function and placing it into the var echo. You were close you had the var echo inside the function and called the function by itself not in the var echo.

Oh! that makes a lot more sense. I wasn't too sure why I was putting the variable echo inside of my function. Thanks again!

Hi,

the second step of this challenge ask you to create a variable called "echo" after the function, which means that need to be created outside the function returnValue. Then set the value of the variable "echo" to be the results from calling the returnValue function, that's basically said that you have to simply call the function and last they recommend that you pass the parameter in a string format.

Like this:

function returnValue(name) {
  return name;
}

var echo = returnValue('Jose');
