Don’t understand how to do get_posts multiple times on same page.

Hi,

I’m very amateur at this. I’m trying to use WordPress to publish blocks of text on certain pages.

For instance on this home page: “https://marinifc.org/index.php” I need to publish a post in the left hand column (board members), and publish a block of news in the middle column (sometimes several posts).

Therefore I created a board list category and a news category, and made entries for each.

So then I need to know how to populate each block with the different categories’ posts.

Right now I’m populating the middle block with this code:
<?php
require('wp-blog-header.php');
?>
<?php
$posts = get_posts('numberposts=5&category=5');
foreach ($posts as $post) : start_wp(); ?>
<div class="post" id="post-<?php the_ID(); ?>">
<h2><?php the_title(); ?></h2>

<div class="entry">
<?php the_content('Read the rest of this entry &raquo;'); ?>
<br></div>
</div>
<?php endforeach; ?>

This works fine. However, if I try to re-use the code to get another category, I get the second entry for that category, but not the first. Possibly I should be using something other than get_posts? I’m a definite novice so if anyone could point me in the right direction, that would be great. I actually did read through a lot of the basic documentation – but still am in a bit of a fog about the whole thing.
