     */
    if (!isset ($_GET['idc']))
        print "<meta HTTP-EQUIV='Refresh' CONTENT='0;URL=menuadmin.php?id=4'>";

    // Pega no registo selecionado para saber o nome 
    // da imagem ($al_img) para depois a eliminar
    $sql = "SELECT * FROM Aluno WHERE al_id = ".$_GET['idc'];
    $result = mysql_query($sql); 
    if (mysql_num_rows($result)!= 0){ 
        $registo = mysql_fetch_assoc($result);
        extract($registo);

        //Elimina a imagem
        unlink("imagens/aluno/".$al_img);
        }

    /* Elimina o registo */
    mysql_query("DELETE FROM Inscricao, 
                             Aluno, 
                             EncarregadoDeEducacao, 
                             Musica_Aluno,

                             Psicologia_Aluno, 
                             SalaDeEstudo_Aluno  
                 WHERE 
                             Inscricao.al_id = Aluno.al_id AND 
                             EncarregadoDeEducacao.ee_id = Inscricao.ee_id AND 
                             Musica_Aluno.al_id = Inscricao.al_id AND 
                             OutrasAtividades_Aluno.al_id = Inscricao.al_id AND
                             Explicacoes_Aluno.al_id = Inscricao.al_id AND 
                             Psicologia_Aluno.al_id = Inscricao.al_id AND 
                             SalaDeEstudo_Aluno.al_id = Inscricao.al_id AND 
                             Inscricao.al_id = ".$_GET['idc'])

    echo mysql_error();
    /* Verifica se deu erro ao eliminar o registo */ 
    if (mysql_error()){
        echo "<script type='text/javascript'>";
        echo 'alert ("Erro ao eliminar ao aluno...");';
        echo "</script>";
    }

    /* Volta à página inicial */ 
    print "<meta HTTP-EQUIV='Refresh' CONTENT='0;URL=menuadmin.php?id=4'>";


?>

The error you give me is as follows:

  

Parse error: syntax error, unexpected T_ECHO in   C: \ xampp \ htdocs \ estagio \ eliminaraluno.php on line 32

What's wrong with the code?

-------- EDITED: ------

I already put ; now gives me more error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE Inscricao.al_id = Aluno.al_id AND Encarregad' at line 1
