Return a numerical function value in Customizer controls

The solution for me ended up being to simply remove the np_post_num() add_action hook altogether, and instead declare get_theme_mod() as the desired variable $option_pg_number. This allowed use of the returned number variable in a separate loop function controlled by $option_pg_number, instead of just printing the returned number value of ‘np_posts_per_page’ on the page.

$option_pg_number = get_theme_mod('np_posts_per_page', '5');

I think this could have been cleared up a lot faster if the WordPress Codex included more documentation on the usage of the various built in features. The codex focuses on setting up the settings and controls, but doesn’t offer much explanation on how to implement the controls on pages.
