Remove all of the HTML.. it does nothing and is not needed.

<?php
session_start();
include "include/db.php";
if (isset($_POST['Submit'])) {
    $email = mysql_real_escape_string($_POST['email']);
    $password = mysql_real_escape_string($_POST['password']);
    $sql = "SELECT username FROM players WHERE email='$email'";
    if ($result = mysql_query($sql)) {
        if (mysql_num_rows($result)) {
          $row = mysql_fetch_assoc($result);
          $_SESSION['username'] = $row['username'];
          header("Location: main.php");
        }
    }
}
?>

Keep this code and try

<?php session_start(); // this session start must be very top of the page 
include "include/db.php";
// 
  if($_SERVER['REQUEST_METHOD'] == 'POST')
   {
    $email = mysql_real_escape_string($_POST['email']);
    $password = mysql_real_escape_string($_POST['password']);

    $sql = "SELECT username FROM players WHERE email='$email' AND password='$password'";
// here you echo the SQL
// if it is found it will show something like this 
// Select username From players Where email='john@abcd.com' AND password='abcdefgh';

$result = mysql_query($sql);
$num_rows = mysql_num_rows($result);

     if ($num_rows > 0) 
 {
       $_SESSION['username'] = $row['username'];
       header("Location: main.php");
     }
 else
 {
 // if it is not found then it will show this error...
  echo "Username not found in Database";
 }
    
}

?>

Now Just make two files login.php and main.php

login.php

please note, I checked this code with my database it is working, some variables name may be mismatched then your code, please check first

<?php 
session_start(); // this session start must be very top of the page 
include ("include/db.php");

// I checked with my database and table, it is perfectly working for me 
//$link = mysql_connect("localhost", "root", '');
//mysql_select_db("********", $link);
// you can comment these lines 

// you don't have to use two pages for login, you can do it in one page 
// if user press the submit button
  if($_SERVER['REQUEST_METHOD'] == 'POST')
   {
   
    $email = mysql_real_escape_string($_REQUEST['email']);
    $password = mysql_real_escape_string($_REQUEST['password']);
// validate the form 

	if (empty($email))
	$msg = "Please enter an email<br>";
	if(!ereg("[0-9a-z]([-_.]?[0-9a-z])*@[0-9a-z]([-.]?[0-9a-z])*\\.[a-z]", $_REQUEST['email'])) 
	$msg .= "Email not Valid<br>";
	if (empty($password))
	$msg .= "Please enter password<br>";

	// if there are no errors you can proceed and check in the DB 

	if (empty($msg))
	{
	//"SELECT username FROM players WHERE email='$email' AND password='$password'";
	$sql = "SELECT username FROM players WHERE email='$email'";
	$result=mysql_query($sql) or die("Your have an error because:<br />" . mysql_error());
	// here you echo the SQL
	// if it is found it will show something like this 
	// Select username From players Where email='john@abcd.com' AND password='abcdefgh';
	$result = mysql_query($sql);


		if(mysql_num_rows($result)!=0)
		 {
		   $array=mysql_fetch_array($result);
		   $usrname = $array['username'];
		   //$_SESSION['username'] = $usrname;
		  	$success = TRUE;
		  		if ($success)
				{
				header("Location: main.php");
				$_SESSION['username'] = $usrname;
				}
		  			   
		 }
		 else
		 {
		 // if it is not found then it will show this error...
		  echo "Username not found in Database";
		 }
    	


	}

}
