    $amplifiers = $_POST['amplifiers'];
    $loudspeakers = $_POST['loudspeakers'];
    $mixers = $_POST['mixers'];
    $catatan = $_POST['catatan'];   

if(isset($_POST['submit']))
{       
    $query="INSERT INTO pasystems (item, microphones, amplifiers, loudspeakers, mixers, catatan) VALUES ('" . $checkBox . "', '$microphones', '$amplifiers', '$loudspeakers', '$mixers', '$catatan')";     

    mysql_query($query) or die (mysql_error() );

}
    else{
    echo "<script type='text/javascript'>alert('Failed!')</script>" . $sql . "<br>" . …
