Widget Area Displacing

Hi all, I’m new to the whole Word Press scene and having a little trouble with a widget area displacing to the bottom of the right hand sidebar after using a custom template.I’ve already had a good search around on the web for advice but I’m informed this is the place to ask, any ideas or opinions would be very much welcome to help me resolve this ??

URL of example: https://www.angrydragongaming.co.uk/?page_id=19

and

The template used:

<?php
/*
Template Name: PageOfPosts
*/

get_header(); ?>

<div id=”content” class=”narrowcolumn”>

<?php
if (is_page() ) {
$category = get_post_meta($posts[0]->ID, ‘category’, true);
}
if ($category) {
$cat = get_cat_ID($category);
$paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1;
$post_per_page = 4; // -1 shows all posts
$do_not_show_stickies = 1; // 0 to show stickies
$args=array(
‘category__in’ => array($cat),
‘orderby’ => ‘date’,
‘order’ => ‘DESC’,
‘paged’ => $paged,
‘posts_per_page’ => $post_per_page,
‘caller_get_posts’ => $do_not_show_stickies
);
$temp = $wp_query; // assign orginal query to temp variable for later use
$wp_query = null;
$wp_query = new WP_Query($args);
if( have_posts() ) :
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<div <?php post_class() ?> id=”post-<?php the_ID(); ?>”>
<h2>” rel=”bookmark” title=”Permanent Link to <?php the_title_attribute(); ?>”><?php the_title(); ?></h2>
<small><?php the_time(‘F jS, Y’) ?> <!– by <?php the_author() ?> –></small>
<div class=”entry”>
<?php the_content(‘Read the rest of this entry ?’); ?>
</div>
<p class=”postmetadata”><?php the_tags(‘Tags: ‘, ‘, ‘, ‘
‘); ?> | <?php edit_post_link(‘Edit’, ”, ‘ | ‘); ?> </p>
</div>
<?php endwhile; ?>
<div class=”navigation”>
<div class=”alignleft”><?php next_posts_link(‘? Older Entries’) ?></div>
<div class=”alignright”><?php previous_posts_link(‘Newer Entries ?’) ?></div>
</div>
<?php else : ?>

<h2 class=”center”>Not Found</h2>
<p class=”center”>Sorry, but you are looking for something that isn’t here.</p>
<?php get_search_form(); ?>

<?php endif;

$wp_query = $temp; //reset back to original query

} // if ($category)
?>

</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>
