   I think this has something to do with me trying to mix strings and arrays....Help please to combine the $option into the array....

   <?php
     $categories = get_categories('child_of=20');
     foreach ($categories as $cat) {
     	$option = '';
   	$option .= ''.$cat->cat_ID.', ';
   
   	echo $option;
   	// This currently outputs: 21, 22,   I need to insert this for the array below like this: $display_categories = array(21, 22,);
     }
   
     // enter the IDs of the categories to display
   $display_categories = array(21, 22,); // I tried entering array($option); here and only get the last category
     foreach ($display_categories as $category) { ?>
     <?php query_posts("showposts=1&amp;orderby=rand&amp;cat=$category"); ?>
     <?php while (have_posts()) : the_post(); ?>
   	<div class="cat-3content">
     		<div align="center"><a href="<?php echo get_category_link($category);?>"><?php echo the_excerpt(); ?></a>
     		</div>
     		<h6><a href="<?php echo get_category_link($category);?>"><?php single_cat_title(); ?></a></h6>
   	</div>
     <?php endwhile; ?>
   <?php } ?>

   You can just set the array in your first foreach loop:

   <?php
   
   $display_categories = false;
   $categories = get_categories( 'child_of=20' );
   
   foreach ( $categories as $cat )
   	$display_categories[] = $cat->cat_ID;
   
   if( $display_categories ) {
   	foreach ( $display_categories as $category ) {
   		query_posts( "showposts=1&amp;orderby=rand&amp;cat=$category" );
   		while ( have_posts() ) {
   			the_post(); ?>
   			<div class="cat-3content">
   				<div align="center"><a href="<?php echo get_category_link($category);?>"><?php echo the_excerpt(); ?></a></div>
   				<h6><a href="<?php echo get_category_link($category);?>"><?php single_cat_title(); ?></a></h6>
   			</div>
   	  <?php
   		}
   	}
   }
   ?>

   Oh dear...sorry about that

   try here... this is using your new code (with thanks)

   http://clients.popcornphotography.com.au/category/events

   I am using photoq which publishes a thumbnail as the_excerpt for each post.

   I want to show a random thumbnail from, and the category title of each child category.

   I have used the old code here to show how I would like it to look

   Cheers and once again Many Many Thanks

   Hmm... look at here:

   query_posts( "showposts=1&orderby=rand&cat=$category" );
   		while ( have_posts() ) {

   See the part that says:

   showposts=1

   This will force the loop to only return one result. Your page is displaying 2 results which is most likely due to the foreach loop the encases the "WordPress Loop".

   Try removing showposts=1 and let me know what happens.

   Hmmm...that didn't work...I'll go back to changing it manually when I put a new client category up..

   Many thanks for your help
