I just want to add 0.1 to the current initiative value of a custom entry in the turn order tracker. I'll add if/else statements later to add to a specific named entry. That part is easy. What I'm having trouble with is setting CurrentRound on the  turn  object and getting that back into the turn order.   on("change:campaign:turnorder", function(obj, prev) {
    if (!Campaign().get("turnorder")) return;
    var turn_order = JSON.parse(Campaign().get("turnorder"));
    if (!turn_order.length) return;
    var turn = turn_order.shift();
    if (turn.id == -1) {
        var CurrentRound = parseInt(turn.pr);
        CurrentRound = CurrentRound + 0.1;
	????
        return;
    }
});
