I think this challenge isn't clear, or is confusing

Why my code isn't working? And I don't understand the point of using a syntax like in this case "redirection" when isn't mentioned at all in this course or at least at the videos before this challenge

story.php
<?php
session_start();
$word1 = htmlspecialchars($_SESSION['word'][1]);
$word2 = htmlspecialchars($_SESSION['word'][2]);
$word3 = htmlspecialchars($_SESSION['word'][3]);
$word4 = htmlspecialchars($_SESSION['word'][4]);
$word5 = htmlspecialchars($_SESSION['word'][5]);

  if (!isset($_SESSION['word'])){
    header('Location: play.php?p=1');
    exit();
  }

include 'inc/header.php';

echo '<h1>My Treehouse Story</h1>';

echo '<p>There once was a(n) ' . $word1;
echo ' programmer named ' . $word2; 
echo '. </p>';
echo '<p>This ' .  $word3; 
echo ' programmer used Treehouse to learn to ' . $word4;
echo ' the ' . $word5 . '.</p>';

echo ' <a class="btn btn-default btn-lg" href="#" role="button">Save Story</a>';
echo ' <a class="btn btn-default btn-lg" href="play.php" role="button">Play Again</a>';
echo ' <a class="btn btn-default btn-lg" href="index.php" role="button">Other Stories</a>';
