how to display count_all_results record to view

I'm sorry but your code doesn't make a lot of sense. The model return count_all_results but the controller return subject_id???
Also, instead of the controller displaying the view, it's the other way around and your view is calling your controller?
There must be missing code you have not post...
Or maybe what you call a controller is a library, but still, you return the count and display the id...
