Mindre mysql fejl

Her er fejlen:

Warning: Unable to jump to row 0 on MySQL result index 2 in /www/docs/users/testeren/community/scripts/giv_point.php on line 23

Og her er min kode:

<?
}
elseif($value=\"1\"){
mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($database);
$query = mysql_query(\"SELECT point FROM brugere WHERE brugernavn=\'$brugernavn\'\");

$point = mysql_result($query, \"point\");

$point = $point + 1;
