Error when evaluating a DAN with 2 utility nodes

[Francisco Javier Díez]

An error occurs when evaluating this DAN by expanding a tree. However, if the node “Costo de solicitar” is removed, the network is evaluated correctly. I guess the problem is because when expanding the two DANs, one for “¿Solicitar introducir?”=”Sí” and the other for “¿Solicitar introducir?”=”No”, the node “Costo de solicitar” has no parent.
