After your newly created returnValue function, create a new variable named echo. Set the value of echo to be the results

After your newly created returnValue function, create a new variable named echo. Set the value of echo to be the results from calling the returnValue function. When you call the returnValue function, make sure to pass in any string you'd like for the parameter.

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

You have declared your echo variable inside the function. You need to declare it outside the function and make it equal to the functions results, like so...

// declare a function that takes one argument
function returnValue(drink) {
  // return the argument
  return drink;
}
// set a variable called echo that is equal to the output of your function (I have given it beer as an argument)
var echo = returnValue("Beer!");
// echo is now equal to "Beer!"
