Another jQuery Challenge

Ok, so i'm gradually working my way through, think i will need to review a couple of times though. For now i've hit another issue with one of the challenges:

Create a method called 'requiredValues' that returns an array of all the values of inputs with the class of 'required'.

==================== My code:

function requiredValues(){ var $inputs = $(.required); var items = new Array();

$inputs.each(function(){ items.push($(this).val()); });

return items;
}

====================

Again any help would be greatly appreciated. I find that the Hints when you get something wrong aren't really that helpful which is ashamed.
