title: Session variable not displaying
body: <p>So I create a session on one page and create a new variable called uName and assign a value.
  I go to another page and try to echo the value but I get an error:"Undefined variable _SESSION"</p>
  
  <p>here is the code:</p>
  
  <p>The page where I start the session and create the variable uName</p>
  
  <pre><code>&lt;?php 
      session_start();
      $_SESSION['uName'] = "Mike";
  ?&gt;
  </code></pre>
  
  <p>The page where I try to echo the variable's value:</p>
  
  <pre><code>&lt;?php echo "My Name is " . $_SESSION['uName'];?&gt;
  </code></pre>
  
  <p>There is nothing else in my code except for a shell of a page just html, head, title, body and paragraph tags, all properly nested.</p>
