Sto realizzando un timer...
Il problema è che quando vado a cambiare il tempo da minuti a secondi mi decrementa di un unità il blocco successivo;
Ovvero se sono su i minuti e schiaccio il pulsante per cambiare i secondi diminuiranno di uno;
Il problema è che non esegue sempre questo errore, dove è l'errore?
