Parents' appeal of the juvenile court's order denying mother's Motion to Vacate a Default Judgment the order denying parents' modification motion to place the children with relatives are dismissed, where: 1) the record does not demonstrate that parents' failure to comply with the writ requirement should be excused for exceptional circumstances constituting good cause; and 2) the parents' contentions actually challenge prior determinations and orders; and thus, none of parents' contentions raised on appeal concerning earlier final appealable orders are cognizable.
