[Plugin: Widget Logic] widget logic an is_page_template(‘category-1.php’)

Thanks for answering.

Before trying with is_page_template, I tried is_category too.
Unfortunately it didn’t work.

My category-5.php, for example, is similiar to and based on Mimbos index.php.
This is my category-5.php. Categories 9-17 are sub-categories of category 5:
Mimbos lead-story is a static page in my category-5.php…

<?php get_header(); ?>
<div id="content">
    <?php /* If this is a category archive */ if (is_category()) { ?>
		<h2 class="pagetitle"><?php single_cat_title(); ?></h2> 	  <?php } ?>
  <div class="feature clearfloat" id="lead"> 	

   <?php
// this is where category-page begins
   query_posts('showposts=1&page_id=102'); ?>
    <?php while (have_posts()) : the_post(); ?>

    <div align="justify"><?php
// this is where the content of category-page gets printed
	the_content(); ?></div>
        <?php endwhile; ?>
  </div><!--END CATEGORY-PAGE-->

  <div id="thirdcol">
<?php
// this is where you enter the IDs of which categories you want to display
$display_categories = array(9,11,13,15,17);
foreach ($display_categories as $category) { ?>
    <div class="clearfloat">
      <?php query_posts("showposts=1&cat=$category");
	    $wp_query->is_category = false;
		$wp_query->is_archive = false;
		$wp_query->is_home = true;
		 ?>
      <h3><a href="<?php echo get_category_link($category);?>"><?php
	// this is where the name of each category gets printed
	  single_cat_title(); ?></a></h3>
      <?php while (have_posts()) : the_post(); ?>
      <?php
// this grabs the image filename
	$values = get_post_custom_values("Image");
// this checks to see if an image file exists
	if (isset($values[0])) {
?>
      <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><img src="<?php bloginfo('template_url'); ?>/images/<?php $values = get_post_custom_values("Image"); echo $values[0]; ?>" alt="" /></a>
      <?php } ?>
      <a href="<?php the_permalink() ?>" rel="bookmark" class="title"><?php
// this is where title of the article gets printed
	  the_title(); ?>&raquo;</a>
      <div align="justify"><?php the_excerpt(); ?></div>
      <?php endwhile; ?>
    </div>
    <?php } ?>
  </div><!--END LEFTCOL-->

  <div id="rightcol">
    <?php
// this is where you enter the IDs of which categories you want to display
$display_categories = array(10,12,14,16);
foreach ($display_categories as $category) { ?>
    <div class="clearfloat">
      <?php query_posts("showposts=1&cat=$category");
	    $wp_query->is_category = false;
		$wp_query->is_archive = false;
		$wp_query->is_home = true;
		 ?>
      <h3><a href="<?php echo get_category_link($category);?>"><?php
	// this is where the name of each category gets printed
	  single_cat_title(); ?></a></h3>
      <?php while (have_posts()) : the_post(); ?>
      <?php
// this grabs the image filename
	$values = get_post_custom_values("Image");
// this checks to see if an image file exists
	if (isset($values[0])) {
?>
      <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><img src="<?php bloginfo('template_url'); ?>/images/<?php $values = get_post_custom_values("Image"); echo $values[0]; ?>" alt="" /></a>
      <?php } ?>
      <a href="<?php the_permalink() ?>" rel="bookmark" class="title"><?php
// this is where title of the article gets printed
	  the_title(); ?>&raquo;</a>
      <div align="justify"><?php the_excerpt(); ?></div>
      <?php endwhile; ?>
    </div>
    <?php } ?>
  </div><!--END RIGHTCOL-->
</div><!--END CONTENT-->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

So, is there any possibility for me to implement my wishes? (On an easy, newbie-way…)
I wish to display a category-widget for categories 9-11 (with “Extended Categories”) while displaying category-5.php (and category-9.php…).

Thanks a lot!
Problem resolved!
