Hi Donald,

The first part of this challenge simply wants you to create a function that returns whatever is input as an argument, like so:

function returnValue(myArgument) {
  return myArgument;
}

The second part says: " 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. "

so, we want to create a new variable called echo that is assigned to the returnValue function. The function has a string passed to it as an argument:

var echo = returnValue("Hello");

The end result of this is that the variable echo now contains the return value of the returnValue function, which in this case is the string 'Hello'. Does that help?

Best, Cena

You are very close, you just need to remove the var inside the function: Your answer is correct, but the questions wants something very simple like this:

function returnValue(a){
return a;
}

It took me a few minutes to understand what the question was asking as well. The question wants you to create the returnValue function that takes in a string:

function returnValue(arg) {
    return arg;
}

The second part of the question is what was confusing for me. You have to create a new variable echo and set that equal to the function you are calling:

var echo = returnFunction("Hello!");
