But as about this error, it is coming because you haven't initialized something before you are trying to use it. as in this case, this.day.title = "day schedule"; You might haven't initialized "this.day" to something(like new Date() or whatever it is here) before using it in the above line. Try to initialize it and then execute your application. -Manu.
