Get checkbox value on form submit and store in a variable using jQuery

Have a form using multiple checkboxes with a class of 'test' (only one of which can be checked however similar to using radio buttons - not my idea btw!).

When the form is submitted I want to get the value of the checkbox that is checked and store it in a variable - can anyone help here?

Cheers!

Chris

$(form).submit(function() {

    var aVariable = $('input.test[type=checkbox]:checked', this).val();

});

.val() returns undefined if called on an empty jQuery object, which would be the case here if no checkboxes are checked.
