Warning: mysql_fetch_array fejl

Jeg får følgende fejl..
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in ny.php on line 5

og skal siges jeg bruger php 4.3.1

<-- ny.php start -->
<?
mysql_connect("localhost","root","");
mysql_select_db("logintest");
$get = mysql_query("SELECT. max(id) as max_id FROM passgen");
$row = mysql_fetch_array($get);
$newid = $row[max_id]+1;
$brugernavn = "frbnet".$newid;

$sesID = md5(time()*time());
$password = substr("$sesID", 0,12);

mysql_connect("localhost","root","");
mysql_select_db("logintest");
$add_profil = mysql_query("INSERT INTO passgen (username, password)" . "VALUES ('$brugernavn', '$password')");
