change

$edit = mysql_query("UPDATE trade SET habbo='$habbo', furni='$furni', amount='$amount', comment='$comment', password='$password' WHERE id = '$id'");

too

$edit = mysql_query("UPDATE trade SET habbo='$habbo', furni='$furni', amount='$amount', comment='$comment', password='$password' WHERE id = '$id'")or die("MySQL Error: <br>".mysql_error());

and post the error message
