max id fejl

jeg kan ikke få det til at virke hvorfor ??

<-- script start -->
<?
mysql_connect("localhost","root","");
mysql_select_db("logintest");
$get = mysql_query("SELECT max(id) as max_id FROM nuke_users");
$row = mysql_fetch_array($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");
$add_profil = mysql_query("INSERT INTO nuke_users (name, user_password, theme, user_lang)" . "VALUES ('$brugernavn', '$password', 'SubSilver', 'danish')");
echo "<br><br><br><br><br><br><br><br><br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<b>Loginnavn :</b> $brugernavn <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<b>Password&nbsp;&nbsp;  :</b> $password";?>
