There's no need to create an echo variable inside the function. They just wanted you to return the value in the parameter.

function returnValue(Ellie) {
  return Ellie; 
}
var echo = returnValue("Ellie");

Here you are calling the returnValue() function with one String argument ("Ellie"). The function takes it and returns it. Then the value is assigned to the echo variable.
