Variable tidak kepanggil, method post

apa ada yg salah dengan pengkodean yang saya buat sampai2 variable nya ga kepanggil.

 <form action="send.php" role="form" method="post" id="reused_form">
                        <div class="row">
                            <div class="col-sm-12 form-group">
                                <label for="message"> Message:</label>
                                <textarea class="form-control" type="textarea" name="pesan"  maxlength="6000" rows="7"></textarea>
                            </div>
                        </div>
                        <div class="row">
                            <div class="col-sm-6 form-group">
                                <label for="grupsms"> Grup:</label>
                               <select  class="form-control" name="namagrup" >
                              <option value= "<?php echo $group["id"]; ?>">  <?php echo $group["namagrup"]; ?>  </option>
                              </select>
                            </div>
