I was creating a jQuery slider and I can't get the slider to even work... Can someone help me out with this question?

Much appreciated if anyone can help!...

Here is my code:
HTML:

<div id="slider img">
<div id="slideshow">
   <div>
     <img src="img1.png">
   </div>
   <div>
     <img src="img2.png">
   </div>
   <div>
     <img src="img3.png">
   </div>
</div>
</div>

CSS:

#slideshow { 
    margin: 50px auto; 
    position: relative; 
    width: 1200px; 
    height: 488px; 
    padding: 10px; 
    box-shadow: 0 0 20px rgba(0,0,0,0.4); 
}

#slideshow > div { 
    position: absolute; 
    top: 10px; 
    left: 10px; 
    right: 10px; 
    bottom: 10px; 
}

jQuery:

$("#slideshow > div:gt(0)").hide();

setInterval(function() { 
  $('#slideshow > div:first')
    .fadeOut(1000)
    .next()
    .fadeIn(1000)
    .end()
    .appendTo('#slideshow');
},  3000);

Full Code:

<------------CSS------------>
</head>
<style>
#slideshow { 
    margin: 50px auto; 
    position: relative; 
    width: 1200px; 
    height: 488px; 
    padding: 10px; 
    box-shadow: 0 0 20px rgba(0,0,0,0.4); 
}

#slideshow > div { 
    position: absolute; 
    top: 10px; 
    left: 10px; 
    right: 10px; 
    bottom: 10px; 
}
</style>



<---------jQuery is here----------->
<script>
$("#slideshow > div:gt(0)").hide();

    .next()
    .fadeIn(1000)
    .end()
    .appendTo('#slideshow');
},  3000);

</script>

</div>

Please Respond a.s.a.p!
Thanks!

Can someone help me out with this question?

What question? There isn't one.

Please Respond a.s.a.p!

"Please" is cool but use of the imperative is not. Also, "a.s.a.p!" is a great way to be ignored.

I just asked if someone can help me fix the code for the slider???

And i'll be sure not to add that in a message

So back to the question... do you see what I did wrong?
