PHP Syntax error, I researched about and couldn't find a solution

I'm creating a loop and I'm having trouble with syntax error, looking the article PHP Parse/Syntax erros and how to solve them I follow the instructions but my problem was not solved. Parse error: syntax error, unexpected 'else' (T_ELSE) in C:\xampp\htdocs\customers\index.php on line 160 still appear and I try to run this code:

 <tbody>
          <?php if ($customers):?>
 <?php foreach($customers as $customer){?>
            <tr>
              <td><?php echo $customer['id']; ?></td>
              <td><?php echo $customer['nome']; ?></td>
              <td><?php echo $customer['usuario']; ?></td>
              <td><?php echo $customer['uno']; ?></td>
              <td><?php echo $customer['editado']; ?></td>
              <td class="actions text-right">
  <a href="view.php?id=<?php echo $customer['id']; ?>" 
  class="btn btn-sm btn-success"><i class="fa fa-eye"></i> Visualizar</a>
              <?php if($_SESSION['UsuarioNivel'] == 3){
                 echo "<a href=\"edit.php?id=<?php echo $customer[id];
  ?>\"class=\"btn btn-sm btn-warning\"><i class=\"fa fa-pencil\"></i> Editar
                  </a>";

               ?> 

              </td>
            </tr>
              <?php } ?>
 <?php else { ?>
<tr>
    <td colspan="6">Nenhum registro encontrado.</td>
</tr>
<?php endif; ?>
          </tbody>
