Display content based on whether there are posts in loop

Hi,

I have a problem that I haven’t been able to wrap my head around yet. In a nutshell, I have a loop with a div wrapper (.partnersBlock) and title (Researchers) that come before the loop itself. What I need to do is set it up so that the div and title don’t appear until a post has been added to that particular loop. This would be set up with conditionals, I just can’t figure out how exactly to write it. Here is my current code:

<?php if (have_posts()) : ?>

<?php query_posts('category_name=researchers&showposts=50&order=ASC'); ?>

        <div class="partnersBlock"><!--this should only appear if there are posts below-->
        <h2>Researchers</h2><!--this should only appear if there are posts below--> 

<?php while (have_posts()) : the_post(); ?>
	<div class="largeProfile">
	<div class="post" id="post-<?php the_ID(); ?>">
	<h3><?php the_title(); ?></h3>
	<?php the_content(); ?>
	</div>
	</div>
<?php endwhile; else: ?>

	<p>Sorry, no posts matched your criteria.</p>

        </div><!--this should only appear if there are posts above--> 

<?php endif; ?>

I’m building the functionality so the user can add posts when they’re ready, but until that point no code is activated. As it stands this is printed:

<div class="partnersBlock">
<h2>Researchers</h2>
</div>

Any help is appreciated.
