form doesn't show options in option field

Hi to all,
my form doen’t show the options in the option field.
I used the wizard to create the form and this is the code that it generated:
[contact-form to='info@turismopesaro.com' subject='Richiesta Offerta PROVA']
[contact-field label='Nome ' type='name' required='1'/]
[contact-field label='Email ' type='email ' required='1'/]
[contact-field label='DATA' type='text'/]
[contact-field label='DATA 2' type='text'/]
[contact-field label='adulti ' type='select' required='1' options='1,2,3,4'/]
[contact-field label='bambini' type='select' required='1' options='0,1,2,3,4'/]
[contact-field label='trattamento' type='radio' options='1,2,3'/]
[/contact-form]

how can I solve it?
thanks in advanced
