problemi con form (select e checkbox) e il javascipt di controllo
Salve, vorrei creare un form dove attraverso una form select possa decidere quante checkbox posso cliccare.
Ho abbozzato un codice ma non funzionano i javascript.
Potreste dirmi dove risiede l'errore/i?
Grazie.
vi allego le bozze dei codici
