Salve è la prima volta che scrivo perchè grazie a questo forum ho sempre trovato le risposte che cercavo.
Però purtroppo non riesco ad uscirne fuori dal seguente problema e chiedo aiuto a tutti voi.
Ho realizzato una classifica che potete vedere al seguente link il problema sta nel fatto che quando vado avanti con la paginazione mi aggiorna correttamente tutto tranne la posizione di classifica che parte sempre da 1.
Sistemando questa cosuccia potrebbe diventare una risorsa utile per tutti
Aiutatemi!!!
Grazie a tutti
Qui il link

il codice è il seguente:
