Pageview error with PHP code

Add the php tags, <?php and ?> to this code snippet:

if ($error == "") {
 echo "Benvindo";
 echo "<a href="index.php">Click aqui para entrar.</a>";
}
 else echo $error;

Code structure has a small error, the correct error:

<?php } if (isset($_POST['submitBtn'])){ ?>
        <div class="caption">Resultado do Login:</div>
        <div id="icon2">&nbsp;</div>
        <div id="result">
        <table width="100%">
          <tbody>
            <tr>
              <td><br />
              <br />
       <?php
          if ($error == ""){
            echo "Benvindo";
            echo "<a href="index.php">Click aqui para entrar.</a>";
          }else
            echo $error;
        ?>
              <br />
              <br />
              <br />
              </td>
            </tr>
          </tbody>
        </table>
        </div>
        <?php } ?>
        </div>
        </div>
