[Includes]

Hello, i wanted add comment on steam profile, what's wrong?
 

var SteamCommunity = require('../index.js');
var ReadLine = require('readline');
var fs = require('fs');

var SteamID = require('steamid');
var CEconItem = require('../classes/CEconItem.js');

var community = new SteamCommunity();
var rl = ReadLine.createInterface({
	"input": process.stdin,
	"output": process.stdout
});

rl.question("Username: ", function(accountName) {
	rl.question("Password: ", function(password) {
		doLogin(accountName, password);
	});
});

function doLogin(accountName, password, captcha) {
	community.login({
		"accountName": accountName,
		"password": password,
		"captcha": captcha
	}, function(err, sessionID, cookies) {
		if(err) {
			
			if(err.message == 'CAPTCHA') {
				console.log(err.captchaurl);
				rl.question("CAPTCHA: ", function(captchaInput) {
					doLogin(accountName, password, captchaInput);
				});

				return;
			}

			console.log(err);
			process.exit();
			return;
		}

		console.log("Logged on!");

		
		
		SteamCommunity.prototype.postUserComment = function(userID, message, callback) {
	if(typeof userID === 'string') {
		userID = new SteamID(userID);
	}

	var self = this;
	this.httpRequestPost({
		"uri": "https://steamcommunity.com/comment/Profile/post/76561198015482752",
		"form": {
			"comment": message,
			"count": 6,
			"sessionid": this.getSessionID()
		},
		"json": true
	}, function(err, response, body) {
		if(!callback) {
			return;
		}

		if (err) {
			callback(err);
			return;
		}

		if(body.success) {
			callback(null);
		} else if(body.error) {
			callback(new Error(body.error));
		} else {
			callback(new Error("Unknown error"));
		}
	}, "steamcommunity");
};

I... I don't even know what you did here. Did you copy the implementation from the code and paste it? Why??
