Advanced IQL - filter by previous multiple choice

[Sergio Rodriguez Perez]

We have a field with the functionality of filter by previous field of the object. 

It's works fine if I select only one value on field: Cliente.

with the IQL: Cliente IN (${Cliente})

The problem is when I selected multiple field on Client.
I don't know  which IQL I should use, I I tried with the followings and doesn't work:

Cliente IN (${Cliente${0}})
Cliente IN (${Cliente})

object HAVING inR(Cliente IN (${Cliente}))
object HAVING inR(Cliente IN (${Cliente${0}}))

object HAVING outR(Cliente IN (${Cliente}))
object HAVING outR(Cliente IN (${Cliente${0}}))

Could you help me?

Thanks
