I need some help here please

I added the code below to display all the pages of my blog, but only the last page is displayed: … 36
What shall I do to display the first 3 pages when I enter the main page?
Something like: 1 2 3 … 36

<?php
$page_links = paginate_links( array(
‘base’ => add_query_arg( ‘paged’, ‘%#%’ ),
‘format’ => ”
‘total’ => $wp_query->max_num_pages,
‘current’ => $_GET[‘paged’]
));

if ( $page_links )
echo “<div class=’tablenav-pages’>$page_links</div>”;
?>

Any hint will be much appreciated.
