Custom jQuery steps; how do I make them clickable?

Question

I'm trying to use an example.

It is all well and nice, but I need to make those steps on top clickable. I tried:

var clickedIndex;
$('#progressbar').click(function(){
    clickedIndex = $(this).attr(id);
});
current_fs=index(clickedIndex);

and updated some other related places, but it didn't get me anywhere enough.

Here is a working example.

Answer 1

$('#progressbar li').on('click', function(){
  var step = $(this).index() - 1;
  $('fieldset').eq(step).find('.next').trigger('click');
});

It triggers a click on the next button of the step that was clicked
