Hi Guys,
I'm kind of stuck in the first question
Call 'map' on the inputs with the class 'required' and return each of their values and store it in a variable named 'values'.
This is the code I'm using
var $required = $(".required");
var values = $required.map(function(){
return $(this).val() == "";
});
return $.inArray(true, values) != -1;
But I keep getting the error
Bummer! You haven't set the variable 'values'
Any ideas?

Gregory, I tried the same code as you before but that's checking for empty values and not all values
The actual answer for 1 of 2 was
var $required = $(".required");
var values = $required.map(function(){
return $(this).val();
});
And the 2 of 2 was adding
$.inArray("Andrew", values);

Treehouse Guest TeacherThis line needs changing return $.inArray(true, values) != -1;
Only $.inArray(true, values);
is required. You can't use return
outside a function. So a syntax error occurs and the script isn't parsed correctly and cannot see values
.

Now if I change the code to this
var $required = $(".required");
var values = $required.map(function(){
return $(this).val() == "";
});
$.inArray(true, values);
I even tried changin to this
var $required = $(".required");
var values = $required.map(function(){
return $(this).val() == "";
});
But now I get 'The values aren't what we're expecting. Please try again.'

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

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