nested javascript queries in parse

Question

I have the code below. Basically I have 3 nested parse queries. One is getting a number of "followers" and for each follower I am getting a number of "ideas" and for each idea I would like to get that idea creator's name (a user in the user table).

The first two nested queries work but then when i try to get the name of the user (the creator of the idea), that last nested query DOES NOT execute in order. That query is skipped, and then it is executed later in the code. Why is this happening please?

var iMax = 20;
                var jMax = 10;
                var IdeaList = new Array();
                var IdeaListCounter = 0;
                var myuser = Parse.User.current();
                var Followers = new Parse.Query("Followers");
                Followers.equalTo("Source_User",{__type: "Pointer",className: "_User",objectId: myuser.id});

                Followers.find({
                    success: function(results) {
                        for (var i = 0; i < results.length; i++) { 
                            var object = results[i];

                            var Ideas = new Parse.Query("Ideas");
                            Ideas.equalTo("objectId_User", {__type: "Pointer",className: "_User",objectId: object.get('Destination_User').id});

                            Ideas.find({
                                success: function(results2) {

                                    for (i=0;i<iMax;i++) {
                                        IdeaList[i]=new Array();
                                            for (j=0;j<jMax;j++) {
                                                IdeaList[i][j]=0;
                                            }
                                    }

                                    for (var j = 0; j < results2.length; j++) { 
                                        var object2 = results2[j];
                                        var ideausername2 = "";
                                        IdeaListCounter++;

                                        var ideausername = new Parse.Query("User");
                                        ideausername.equalTo("objectId",object2.get('objectId_User').id);

                                        ideausername.first({
                                            success: function(ideausernameresult) {
                                                ideausername2 = ideausernameresult.get("name");
                                            }
                                        });

                                        IdeaList[IdeaListCounter,0] = object2.get('objectId_User').id + " " + ideausername2; //sourceuser
                                        IdeaList[IdeaListCounter,1] = object2.get('IdeaText'); //text
                                        IdeaList[IdeaListCounter,2] = object2.get('IdeaImage'); //image
                                        IdeaList[IdeaListCounter,3] = object2.get('IdeaLikes'); //likes
                                        IdeaList[IdeaListCounter,4] = object2.get('IdeaReport'); //reports

Your nested query is asynchronous.
