Always shows Undefined index 'confirmPassword'

Question

I am trying to run the below code... HTML...signup.html

<div>
    <label for="create-password">Create Password</label>
    <input id="create-password" type="password" placeholder="Atleast 6 characters" name="password" required>
</div>
<div>
    <label for="confirm-password">Confirm Password</label>
    <input id="confirm-password" type="password" placeholder="Atleast 6 characters" name="confirmPassword" required>
</div>

PHP Part

$password = $_POST['password'];
$confirmPassword = $_POST['confirmPassword']; 
if($password != $confirmPassword)
        echo "Passwords do not match";

Whenever i try to run this it says

Notice: Undefined index: confirmPassword in E:\xampp\htdocs\Nishat's Web Design\signup_process.php on line 26 Passwords do not match

I dont understand why it is not considering the second input name = confirmPassword... If someone helps then it would be appreciateable

There's no problem in your code. Just check that you specified form method to post I've tried code and it's working fine, and always first check input field isset or not. Here's my code

<?php
if(isset($_POST['submit']))
{
$password = $_POST['password'];
$confirmPassword = $_POST['confirmPassword']; 

if($password != $confirmPassword)
echo "Passwords do not match";
}
?>

HTML:

<html>
<head>
    <meta charset="utf-8">
    <title></title>
</head>
<body>
<form method="post">
 <div>
                    <label for="create-password">Create Password</label>
                    <input id="create-password" type="password"
                    placeholder="Atleast 6 characters" name="password" required>
                </div>
                <div>
                    <label for="confirm-password">Confirm Password</label>
                    <input id="confirm-password" type="password"
                    placeholder="Atleast 6 characters" name="confirmPassword" required>
                </div>
                <input type="submit" name="submit">
    </form>
</body>
</html>
