Keep Getting Member Function Error

Hold on, never mind. I realized I made an error later on down where I tried to call the variable and I had an incorrect capitalized letter. That being said, I now get the following error: Fatal error: Call to undefined method WP_Query::the_posts() in C:\xampp\htdocs\wordpress\wp-content\themes\sports\home.php on line 21.

Any help on that.

What does line 21 on home.php look like along with the code for a few lines above it?

Yeah, sorry about that. Thought of it after I shut down last night.

Here is line 21:
($featuredposts->have_posts()) : $featuredposts->the_posts();

Here is the entire code for slideshow:

<?php
		$featuredposts = new WP_Query();
		$featuredposts->query("showposts=4&cat=5");
		while ($featuredposts->have_posts()) : $featuredposts->the_post();
	?>

	<div id="slide-<?php echo $slide_id; $slide_id++;?>">
		<a href="<?php the_permalink() ?>">
		<?php the_post_thumbnail( 'slideshow-photo' ); ?>
		</a>
	</div>

	<?php endwhile; ?>

	<ul id="slide-nav">
		<?php $nav_id=1; while
		($featuredposts->have_posts()) : $featuredposts->the_posts(); ?>
			<li>
				<a href="#slide-<?php echo $nav_id; ?>">
					<span>
						<?php the_post_thumbnail( 'nav-image' ); ?>
					</span>
					<?php the_title(); $nav_id++;?>
				</a>
			</li>
		<?php endwhile; ?>

Okay, so kept looking at the code and I figured out the problem. The second the_post() statement had an ‘s’ at the end of it (result: the_posts() ). So I’m not getting the error anymore; however, the slideshow isn’t working (see this link). The tutorial says to use wp_enqueue_scripts() to get the ‘jquery’, ‘jquery-ui-core’ and ‘jquery-ui-tabs’ files. Not sure why it’s not working.

And finally, my CSS skills are a bit on the bad side, obviously. If anyone wishes to help me, message me and I’ll see if I can get you the files as soon as possible. Thanks in advance.
