Correction: Reconfiguring a Running Replica "Set cfg.members[3].voting = 0" should be "Set cfg.members[3].votes = 0"

votes is the correct name of this attribute that we are to update
Ex:
{
“_id” : 3,
“host” : “m103-repl:27004”,
“arbiterOnly” : false,
“buildIndexes” : true,
“hidden” : true,
“priority” : 0,
“tags” : {

                    },
                    "slaveDelay" : NumberLong(0),
                    "votes" : 0
            },

My bad. I’m mistaken. The lesson spelled it correctly.
