Look, from your code, your session variable is being initialized after sending the data, I mean after clicking the submit button of your first page. But when you send the from it is going to the next page without initialize the session variable. That's mean the session variable is not being initialized. So, you can create another page which is linked up between this two page. Create another page named linkingPage.php. Change the first page action to linkingPage.php and cut those lines php code and paste it to the newly created page

<?php
    session_start();
    if(isset($_POST['Submit1']) ){

        $firstname = $_POST['first'];
        $lastname = $_POST['last'];
        $firstname=ucwords($firstname);

        $_SESSION["firstname"] = $_POST['first'];
        $_SESSION["lastname"] = $_POST['last'];

        header('Location:main1.php');
    }
?>

last two line is commented out, cause now it's unnesseceray. Now run the code and I hope it will work. Enjoy.

A session variable can be used throughout the website, on any page

However, could this be an error with your POST? try simply setting the session variables to a string, and see if they are retrieved on the other webpage
