Can't get this to work - Map Function from validation

I've looked at everything else, and thought I had this but it keeps saying the same thing. "You haven't set the variable 'values'". But I have: this is the code I'm submitting -

var required = $(".required");

function requiredValues(){

var values = required.map(function(){return $(this).val();});

}

What you've written could pass the code test if you made values a global variable and you also called your function so that the map code can be executed:

var required = $(".required");
var values;

function requiredValues(){

values = required.map(function(){return $(this).val();});

}

requiredValues();

But you're writing more than what is required for task 1. You only need the line that's calling the map function.
var values = required.map(function(){return $(this).val();});

The directions would have been more specific if they wanted you to put it in a function.
