Highlight navigation

Hello all.
I know there are several posts on this, but I’m still a bit confused – hope someone can clarify:

I have a sidebar for navigating my projects. https://rumlab.dk/blog/rumlab/
The code looks like this:

<?php if (in_category('design')) {
	echo '<span class="current-category">Design</span>';
} else {
	echo 'Design';
}
?>
<ul>
<?php

$IDOutsideLoop = $post->ID;
global $post;

$myposts = get_posts('category=3');
foreach($myposts as $post) :
?>

<li <?php
if(is_single() && $IDOutsideLoop == $post->ID) 

{
echo " class=\"current\"";
}
?>>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

<?php endforeach; ?>
</ul>

<?php if (in_category('architecture')) {
	echo '<span class="current-category">Architecture</span>';
} else {
	echo 'Architecture';
}
?>

<ul>
<?php

$IDOutsideLoop = $post->ID;
global $post;

$myposts = get_posts('category=4');
foreach($myposts as $post) :
?>

<li <?php
if(is_single() && $IDOutsideLoop == $post->ID) 

{
echo " class=\"current\"";
}
?>>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

<?php endforeach; ?>

</ul>

Found the code in the forums. Problem is, the current class is not applied in the repeated section.
I need to do this several times for different categories. Anyone?

Thanks

Morten
