jQuery if no carousel shown open certain carousel

[367]

Hi

I have window that contains 4 carousels with some text. At start first 3 are hidden and last one (#conf) is shown. When i click on title (h3) of carousel it does .fadeToggle for it and .fadeOut for other 3 carousels.
Now, i need last carousel to be opened when no other carousel is shown.
Here is code i have:

$(document).ready(function() {
$('div.ci> div').hide();
$('div.ci> div#conf').show();
$('div.ci> h3').click(function() {
$(this).next('div').fadeToggle(500)
.siblings('div:visible').fadeOut(0)
});
});

Any help would be great
