wp_page_numbers plugin did not work

Here is my case:I have a php file category-22.php set up,and I use query_posts method to query the posts and wp_page_numbers plugin to page the posts.I wonder if there is anything wrong with my code,when i click the second page,the url(https://……/tutoriol/page/2)is right,but content still stay the first page,i searched the similar posts in the forum,it told me that my query_posts method should add get_query_var,so I add it in my code `<?php $paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1;
query_posts(‘cat=22&offset=1&paged=$paged&posts_per_page=10’); ?>`,but It didn’t work,i tried every means i could,but the result still the same.I have my code attched,hope you can help me.I really thanks to you.

<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('cat=22&offset=1&paged=$paged&posts_per_page=10');?>
<?php if(have_posts()):?>
<?php while(have_posts()):the_post();?>
<div class="listitem">
<h1><?php the_title();?></h1>
<?php if(get_post_meta($post->ID,'topic_image','true')):?>
<?php $image=get_post_meta($post->ID,'topic_image','true');?>
<img src="<?php echo $image;?>" />
<?php else:?>
<img src="<?php bloginfo('template_url')?>/custom_images/default.jpg" />
<?php endif;?>
<?php the_excerpt();?>">[MORE]
</div>
<?php endwhile;?>
<?php if(function_exists('wp_page_numbers')) : wp_page_numbers(); endif; ?>
<?php endif;?>
