How to send repeating table to WebService

[Sifri]

Hi All

I have a WebService to receive a parameter struct, for example:

public struct GroupMemberShip
{
public string nombreGrupo;
public bool esMiembro;

public GroupMemberShip(string NombreGrupo, bool EsMiembro)
{
nombreGrupo = NombreGrupo;
esMiembro = EsMiembro;
}
}

I want receive and submit data in a Form(InFoPath 2007), i create a data
source and I receive the data in the repeat table, for example 3 rows. Find
this Ok.

But my problem is to send the modified data. I create a button submit but is
impossible send the all rows, only send 1 row. Why¿?.

¿How i can send the entire repeat table to a WebService?.

Sorry, my english level is little...

Regards
