CB Conditional don't work fine

I need two register screens.

When register a normal user then show two tabs, but when register a professional user then show another tabs.

I try use cbconditional when this values but don't work fine.

Field: valor
valor:get_p
operator: igual que
valor: 1
Mode: show
Registro: desactivado

I try hide "Maternidad" tab in www.todomaternidad.com/date-de-alta-profesional-de-la-maternidad/registers?p=1
