I am new to html/javascript/CSS and I am trying to make a score page for a quiz I am making. I am having the issue that on my score page, although I have a working alert that displays the number I want, when I try to put it into the inner HTML nothing happens. I am getting the number from the URL and it would be formatted like "address.com/blah?=9". I am not sure if my error is a fundamental error or a basic syntax error. The code is meant to display the number in the URL right before the /10 any help is much appreciated, Thanks!
<!DOCTYPE html>
<html>
<style>
body{
background-color: pink;
text-align: center;
}
div{
display:inline-block;
}
</style>
<head>
<title>Submission Form</title>
</head>
<script>
var x = document.URL;
var QIndex = x.indexOf("?") + 2;
var questionCorrect = x.substring(QIndex,QIndex+2);
alert(questionCorrect);
document.getElementById("QCor").innerHTML = questionCorrect;
</script>
<body>
<h1>Thank You</h1>
<p>Here is your score:</p>
<div id="QCor"></div>
<p> /10</p>
</body>
</html>
