Add Template to Add-on

I'm using an unsupported add-on and am trying to figure out how to display some information on a new page node from that add-on, for private usage. The page node is to display information in a certain format but when I created a new page and copied the coding from one of this add-on's template to the page's template as a test, it didn't display any of the specific information.

How would I go about doing this? I'm a bit stumped at the moment.
I copied the coding from one of the add-on's templates and put it into the page node's template. I added the add-on's ControllerPublic class and Method, or so I thought and I get the following error:

Fatal error: Using $this when not in object context in -blocked out path- on line 122
Very confused.

If you're writing a static class, you can't use $this. If you can show us an example of your code, maybe we can help you better.
I'm not writing a class. I'm just trying to display information that an add-on already does on one of its pages but on a page node. The add-on displays a list of everything with no filter options. I've already set it up to show only a certain thing but being as it is hard coded, it removes the rest. I don't want this so I'm looking to have a page node for each filter. The problem is having that information show up on a page node.

So the question do I port the information to a page node in addition to copying the template code into the page node's template?
