Pues segun lo que veo si. Te dejo el codigo completo.
Código PHP:
// Datos usuario
$id = $account_extra['id'];
$avatar = $account_extra['avatar'];
$blizz = $account_extra['blizz'];
$class = $account_extra['class'];
$firstName = $account_extra['firstName'];
$lastName = $account_extra['lastName'];
$character = $account_extra['character'];
// Script
$votenew = ($account_extra["vote_points"] - $shop1["vote_points"]);
$creditnew = ($account_extra["credit-store"] - $shop1["credit-store"]);
$result = mysql_query("UPDATE $server_db.users SET users.vote_points = '".$votenew."', users.credit-store = '".$creditnew."' WHERE users.id = '".$id."' AND users.avatar = '".$avatar."' AND users.blizz = '".$blizz."' AND users.class = '".$class."' AND users.firstName = '".$firstName."' AND users.lastName = '".$lastName."' AND users.character = '".$character."'");
