WP-Paginate not working with Custom Pagenavi function for index

Greetings, I am trying to use my custom pagination code I have from WP-Page navi in conjunction with the plugin WP-Paginate (so that I may deply pagination for my COMMENTS)

So here is the wp page navi code in my functions.php:

https://pastebin.com/MMvJLDsx

so when I activate the wp-paginate plugin I then try to put

<?php if(function_exists('wp_paginate_comments')) {
    wp_paginate_comments('range=4&anchor=2&nextpage=Next&previouspage=Previous');
} ?>

Into my single.php file..

What am I doing wrong?
