ajax() not working IE - parser error undefined - JavaScript and CSS

Hi, sorry for my english, I need help with a script please.

I have a star rating script on my website, that work fine on firefox and safari but but on IE.

My html:

<script type="text/javascript" src="loco/rate-product-ajax.js"></script>

<form>

  <input class="star rate" type="radio" name="rate" value="1" />

  <input class="star rate" type="radio" name="rate" value="2" />

  <input class="star rate" type="radio" name="rate" value="3" />

  <input class="star rate" type="radio" name="rate" value="4" />

  <input class="star rate" type="radio" name="rate" value="5" />

</form>

I call two files:

<script src="http://code.jquery.com/jquery-latest.js"></script>

<script type="text/javascript" src="loco/jquery.rating.js"></script>

rate-product-ajax.js

$(document).ready(function() {

						   

var some_product_id=77;

 //let's say it's product with id=1, if you have application you will change this variable programatically


getRating(some_product_id);


function getRating(id){

	$.ajax({

		type: "GET",

		url: "loco/rate-product.php",

		dataType : 'json',

		processData: false,

		data: "do=getRate&product_id=" + id,

		cache: false,

		async: false,

		success: function(result) {

			avg=result.avg;

			sum=result.count;

			$("#votes").html;

			$(".vote_count").html(sum + " vote(s)");

			$('.rate').rating('select',avg);

		},

		error: function(jqXHR, textStatus, errorThrown) { 

    alert(textStatus+' - '+errorThrown);

		}

	});

}


$('.rate').click(function(){

	$.ajax({

		type: "GET",

		url: "loco/rate-product.php",

		dataType : 'json',

		data: "do=rate&product_id=" + some_product_id + "&rate="+$(this).text(),

		cache: false,

		async: false,

		success: function(result) {

			avg=result.avg;

			sum=result.count;

			$("#votes").html("Average:" + avg);

			$(".vote_count").html(sum + " vote(s)");

			$('.rate').rating('select',avg);

			$('input',this.form).rating('readOnly',true);

			//$('input',this.form).rating('disabled',true);

			//$('input',this.form).rating('return',false);

			$('.rate').unbind('click');

			

		},

		error: function(jqXHR, textStatus, errorThrown) { 

    alert(textStatus+' - '+errorThrown);

		}

	});

});

});

My php file

function getRate() {

	$sql= "select ifnull(round(sum(rate)/count(*),0),0) avg, count(*) count from rate where product_id=" . $_GET['product_id'];

	if($result=mysql_query($sql)) {

		if($row=mysql_fetch_array($result)) {

			$rate['avg'] = $row['avg'];

			$rate['count'] = $row['count'];

			echo json_encode($rate);

		}

	}

}



/* $ip = $_SERVER["REMOTE_ADDR"];

	

	$product = $_GET['product_id'];

	$valideip = "SELECT * FROM  rate WHERE ip = '$ip' AND product_id = '$product' ";


	$row_ip = mysql_num_rows($valideip);

	

	if($row_ip < 1)

*/



// function to insert rating

function rate() {

	$ip = $_SERVER["REMOTE_ADDR"];

	

	$product = $_GET['product_id'];

	$valideip = "SELECT * FROM  rate WHERE ip = '$ip' AND product_id = '$product' ";

	

	$sql = "insert into rate (product_id, rate, ip) values (" . $_GET['product_id'] . ", ".$_GET['rate'].",'$ip')";

	

	if($result=mysql_query($sql)) {

		getRate(); //call retrieve from getRate function

	}

}




if(!empty($_GET['do'])) {

	include 'config.php';

	include 'opendb.php';  //open database connection

	

	if($_GET['do']=='rate'){

		// do rate

		rate();

	}

	else if($_GET['do']=='getRate'){

		// get rating

		getRate();

	}

}

On Internet explorer an error appear: parsererror undefined I don't know if the script can open rate-product.php. :cursing:
