Read a Javascript cookie with PHP

I have some javascript code that sets a cookie and when i try to read that cookie with php it says that it is undefined. 

Notice: Undefined index: scorecount in C:\xampp\htdocs\Contest\score.php on line 44

I am using xamp to run and test the php on my computer, could that be the reason why it is not reading the cookie?

Here is my code

<!DOCTYPE html>
<html>
    <head>
        <title>PHP Written Test</title>
    </head>
    <body style="background-color:#ADD8E6; margin-left:25%;">
        <?php include 'variables.php';?>
        <?php include 'functions.php';?>
        <?php     
            session_start();   
            $x = 1;
            $y = 0;
            $score = 0;

            while ($x <= 20) {  
                $a = $_POST["question" . $x];
                $b = $_SESSION['correct'][$y];
                $c = $_SESSION['question'][$y];

                if (trim($a) == trim($b)){      
                    $score++;   
                } else {
                    echo "$c<br>Your answer was: $a<br>The correct answer is: $b<br><br>";  
                }

                $x++;
                $y++;
            }

            echo "$score/20";
            echo $_COOKIE["scorecount"]; 
    ?>
    </body>
</html>

I would post a picture to prove that the cookie is set correctly but i dont have enough rep. When I look at all the cookies in my web browser the cookie "scorecount" is there and is set correctly, if someone could please tell me what I am doing wrong that would be great thanks!

My JS that sets the cookie

function getCookie(c_name)
{
   alert("Im in getCookie");
   var i,x,y,ARRcookies=document.cookie.split(";");
   for (i=0;i<ARRcookies.length;i++)
  {
     x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
     y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
     x=x.replace(/^\s+|\s+$/g,"");
     if (x==c_name)
    {
    return unescape(y);
    }
  }
}

function setCookie(c_name,value,exdays)
{
   alert("Im in setCookie " );
   var exdate=new Date();
   exdate.setDate(exdate.getDate() + exdays);
   var c_value=escape(value) + ((exdays==null) ? "" : ";               

   expires="+exdate.toUTCString());  
   document.cookie=c_name + "=" + c_value;
   alert("Cookie Set");
}

function checkCookie(end)
{
   alert("Im in checkCookie");
   document.getElementById('full').ondragstart = function noDrag() { return false; };
   var score=getCookie("scorecount");
if (score!=null && score!="")
  {
     if(end == 'yes')
     {

     score = score - 1;




    return score;

     alert("Your score is " + score);

    }
    else 
    {

     score=1;
  if (score!=null && score!="")
    {

       setCookie("scorecount",score);
       //alert("Your score is " + score);
    }
  }
}

function correct(pgnmbr)
{
   var val;


   val = getCookie('scorecount');
   val = parseInt(val)+ 1;
   setCookie('scorecount',val);
   location.href = loc();
   alert(val);

}
function correct2(pgnmbr)
{
   var val;


   val = getCookie('scorecount');
   val = parseInt(val)+ 1;
   setCookie('scorecount',val);
   location.href = loc2();


}

   var clicks = 0;
function wrong(pgnmbr)
{   

   clicks++;
 if(clicks < 3)
 {

   alert("wrong try again");

 }
 else
 {  
   alert("you have exceeded your amount of trys");


    location.href = loc();
}
}

document.getElementsByClassName('box1')[0].addEventListener('click', correct, false);

document.getElementsByClassName('bg')[0].addEventListener('click', wrong, false);

Ok I solved my issue apparently you can only read a cookie that was set on the same domain... #Duh#Noobie Thanks for the suggestions though guys!!

Try to send the cookie content with an ajax call to the php function that you want to use to read the cookie, good luck
