Znalazłem na tej stronie http://www.ssdtutorials.com/tutorials/seri...checkboxes.html fajny tutorial do usuwania wielu rekordów, próbuje go połączyć z paginacją od wczoraj ale nic mi nie wychodzi, gdyby ktoś chciałby mi pomóc byłbym bardzo szczęśliwy, z góry dziękuję za pomoc.

oto połączony skrypt z paginacja - gdzie paginacja nie działa
