Grazie per l'aiuto e la risposta veloce

Answer 1

Oo vedo che non qualcosa di grande, ma vorrei che si vivamente a sostituire i vostri stati di visualizzazione con solo una soluzione "normale" basta usare i valori dalle vostre caselle Rad Combo sua strada più facile ma di sicuro questa non è una vera soluzione per te problema causa visto che è davvero strano non vedo l'errore qui, per me sembra tutto per me Ok. ma se rispedisci il tuo codice aggiornato con alcuni commenti. !

Se avete problemi e non esitate a chiedere ¨

PS: Se si finisce la soluzione dare in contatto con !!
