[jQuery] problem with selecting next element

[jQuery] problem with selecting next element


Hello everyone!
I have sth like that :
<span class="first">fsat</span><span>..</span><span>...</span>....
<div>should be toggled</div>
<span class="first">fsat</span><span>..</span><span>...</span>....
<div>should be toggled</div>
<span class="first">fsat</span><span>..</span><span>...</span>....
<div>should be toggled</div>
....
and when I try:
$("first").toggle(
function(){
$(this).next("div").fadeIn("slow");
},
function(){
$(this).next("div").fadeOut("slow");
}
);
it doesn't find the next div. Why is that?
