Saya mau tanya supaya data dari database bisa muncul di halaman mpdf bagaimana ya?

Permasalahan : Warning : mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\table\rep.php on line 15 Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\table\rep.php on line 18

Script nya :

14. $jum=mysql_query("SELECT COUNT(*) as jml FROM smc WHERE data_user ='" . $_GET['data_user'] . "' AND tgl_masuk BETWEEN '" . $_GET['tgl_masuk'] . "' AND '" . $_GET['tgl_keluar'] . "' AND alamat = '" . $_GET['alamat'] . "'"); 15. $count = mysql_fetch_array($jum); 16. $a = mysql_query("SELECT * FROM data_user WHERE dtr_pa ='" . $_GET['dtr_pa'] . "' AND tgl_terima BETWEEN '" . $_GET['tgl_awal'] . "' AND '" . $_GET['tgl_akhir'] . "' AND golongan = '" . $_GET['jns_periksa'] . "' order by tgl_terima asc"); 17 $doc = mysql_query("SELECT * FROM smc WHERE id_pasien ='" . $_GET['id_pasien'] . "'"); 18. $nm_doc = mysql_fetch_array($doc);
