[MySQL][PHP]Pobieranie danych z mysql Opcje

[saviola15]

Witam mam tutaj skryp który przerabia cenę po rabacie. Chciałbym żeby na początku wyciągnął samą cenę z tabeli product.price i można było ją wywołać w innym pliku naprzykład $pri;

na początku kodu to dodałem:
$product.price = $pri; Jak to dodałem strona mi się wywaliła.. http://www.pneumaticon.pl/presta/ Plik : GroupReduction.php
