I'm not sure what you mean by "copied the code" since it seems unnecessary. To get what you want go to the product in admin and create a new option and choose "Custom text field" as the Option type (this will allow the customer to enter some text, and it will displayed with the order). Then you can make it show up in whatever order you want by adjusting the "OrderBy" field.

Edit: If all you are trying to do is place a "line" somewhere, that is a simple <hr> as I said before.
