Thats because this file wasn’t really built for what you’re trying to do. It was originally designed to show the home widgets, or the blog if you dont have any widgets by default. If you need anything beyond that, then the file would have to be customized in order to achieve what you’re looking for.
I usually offer the code if its something quick and easy, but somethings (like this) can take a while to customize/code. Thats why I would recommend searching for tutorials, or hiring someone to develop a custom template for you.
