The assignment to echo will never be reached because when you return a value from a function it exits the function. You should place your assignment to echo outside of the function (below it) and make sure you call the function.

Thanks ryan, How do I call the function after I have moved echo out of it?

var echo = returnValue(<input goes here>);
