I am making a form in which I ask the sex of teh person and I think
i should use a option button :
0 Masculine
0 Femenine

and the result is kept in a field of a table (Is a caracter M or F).
well the value is kept but the bitton disappeared!!!
And if the value is not kept the option selected doesn´t disappeared?

I don´t know why
thanks!!!
