    Friend. Use this way, There will be no "Undefined variable message" and it will work fine.

    <?php
    if(isset($_POST['SubmitButton'])){
        $price = $_POST["price"];
        $qty = $_POST["qty"];
        $message = $price*$qty;

    <html>
    <head>
        <title></title>
    </head>
    <body>
        <form action="#" method="post">
            <input type="number" name="price"> <br>
            <input type="number" name="qty"><br>
            <input type="submit" name="SubmitButton">
        </form>
        <?php echo "The Answer is" .$message; ?>

    </body>
    </html>

    Try this... worked for me

    <form action="submit.php" method="post">
<input type="text" name="input">
<input type="submit">
</form>

    ------ submit.php ------

    The best way to stay on the same page is to post to the same page:

    <form method="post" action="<?=$_SERVER['PHP_SELF'];?>">
