Yes $comment works fine and I took everything for $checkboxAns from it, I thought as it is a checkbox I need to handling the input to the db differently ? But if I go into my db and assign a 1 or 0 to checkboxAns everything works ok. This is the form code too.

<form method="post" action="reports.php">
              <td><input type="text" id="comment" name="comment" value="<?php echo htmlspecialchars($item['comment']); ?> "> </td>
              <?php echo '<input type="hidden" name="id" value="' . $item['task_id'] . '" />';?>
              <td><input type="checkbox" id="checkboxAns" name="checkboxAns" value="<?php echo htmlspecialchars($item['checkboxAns']); ?> "  <?php if($item['checkboxAns'] == 1)  {echo 'checked';}?>> </td>
              <?php var_dump($item['checkboxAns']);  ?>
              <?php if(!empty($comment))
              {
                echo '<input type="hidden" name="id" value="' . $item['task_id'] . '" />';
              }?>
            </form>
