Parse Cloud Code Increment Trouble

I am not familiar with Javascript or Cloud Code and only began using CC yesterday. This seems like an extremely simple task, but I am banging my head trying to figure this out.

When a 'Chat' object is saved to parse, I want to increment the 'numberOfMessages' (of type Number) field of a 'ChatRooms' object, where ChatRooms.objectId = Chat.RoomId

Easy. I've tried many many things, here is the latest which is straight from the Parse Docs.

Parse.Cloud.beforeSave("Chat", function(request, response) {
                  query = new Parse.Query("ChatRooms");
                  query.get(request.object.get("roomId"), {
                            success: function(post) {
                            post.increment("numberOfMessages", 1);
                            post.save();
                            response.success();
                            },
                            error: function(error) {
                            console.error("Got an error " + error.code + " : " + error.message);
                            response.error();
                            }
                            });
                  });

In this example, there error is:

ReferenceError: response is not defined
at query.get.success (main.js:7:33)
at Parse.js:2:7706
at e (Parse.js:2:6486)
at Parse.js:2:5935
at Array.forEach (native)
at Object.x.each.x.forEach [as _arrayEach] (Parse.js:1:664)
at c.extend.resolve (Parse.js:2:5886)
at e (Parse.js:2:6621)
at Parse.js:2:5935
at Array.forEach (native) (Code: 141, Version: 1.5.0)

Any pointers are appreciated.

And finally.. are there any good resources for learning Javascript as it relates to Parse Cloud Code? My search didn't turn up anything useful. Thanks!

Replace

request.object.get("roomId").id

with

request.object.get("roomId")

since roomId is a string rather than a Room object.

Update: Also, add response.success() to the success handler and response.error() to the error handler to let Parse.com know you're done.
