I saw your variable at the top of the page, but I couldn't find where you were trying to display it.

It seems as though you haven't filled out your <form> declaration. It is not set to method="post" so the $_POST["submit"] is not available so the variable $results is not being set.

Since your submit button doesn't have a value declared $_POST["submit"] does not have a value so if($_POST["submit"]) is false so the $results variable never gets set. You can either add a value to your submit button, or set if($_POST["submit"] == "")

Just adding to what Ron said, if you are going to echo the $results variable without checking to see if it's set first, then you need make sure it's set. Therefore when you declare it up top, rather than just using

<?php 
    if($_POST["submit"]){
        $results = "form has submitted"; 
    }
?>

use 

<?php 
    if($_POST["submit"]){
        $results = "form has submitted"; 
    }else {
              $results = "no current submissions ";  //or something like that
       }
?>
