You were pretty close.

But you don't have a variable named "money", that's just the parameter name in your function. You wouldn't need a variable anyway, you just need to assign echo directly with the result of calling your function. Also, remember that JavaScript is case-sensitive, so "var" must be spelled in all lower case:

var echo = returnValue("here's ya cash");

The instructions say: Set the value of echo to be the results from calling the returnValue function.

When calling the returnValue function, like this:

returnValue("My String");

it will automatically return the value, because of the return statement you declared in the function. In the above example however, you aren't doing anything to "catch" what it's returning or to save it. It's being returned but since nothing is catching it, it effectively disappears.

So you want to assign the result of calling that function into a new variable--in this case, a variable called echo.

var echo = returnValue("MyString");

If a function returns a value but no variable is there to catch it, does it really return?

Well...it will certainly get harder. At times a lot harder. But at that same time, things that were once hard become easy and you don't even have to think about them anymore. Learning the fundamentals of any language is daunting at first and you'll probably have times where you feel like you're getting a good handle on things for awhile but then a new concept will be introduced that makes you feel lost all over again.

It's all a matter of how much time and practice you want to commit to it, but there's lots of people here willing to help along the way.

If you really want to return same money, just add semicolon like this return money;
