numeric pagination

Hi all

Can someone tell me what I need to do to get the pagination not in text but in numbers?

I’ve installed the plugin Page-Navi and I added script to index.php
(<?php
if ( function_exists( ‘wp_pagenavi’ ) ) {
wp_pagenavi();
} else {
the_posts_navigation();
}
?>)

In admin-view it is okay but on the the site itself is it not… so I guess I did something wrong somewhere… Who can help me out?
