You don't need to have the () around the return value, just a space.

so... here

function returnValue(string){
    return string;
}

var echo = returnValue('any text here')

when you have a method that hs a return, you have to put it into a variable and you have to call it and specify the argument between prentecies, if it is a string argument, you put it inside ' ', if it is a number you write as it is.
