Hælp til input i tabel..

Hvorfor virker dette ikke?
-------------------------------------------------
<?php

$conn = mysql_connect("mysql.vipz.dk", "xxx", "xxxx");

mysql_select_db("vipzdk");

$insertSQL = "insert into chs_members (nick, navn, alder, fav_map, fav_wea, fav_tea, comments)

values ('$nick', '$navn',  '$fav_map', '$fav_wea', '$fav_tea', '$comments'";

mysql_query($insertSQL) or die(mysql_error());

header("Location: members.php");

?>
-------------------------------------------------

Fejlen: "You have an error in your SQL syntax near '' at line 3"

Kan ikke lokalisere det...  :-(
