Please help with this code!

I am not a programmer but need to do a slight adjustment to a drupal site. Can anyone help?

The code below displays 2 "news" post items on the home page. How can I make it display 3 or 4 items?

Here is the home page link: http://www.refbc.com

Thanks for any help!

<div class="holder">
	<div class="home-left-side">
		<div class="title">news &amp; Events</div>
		<table width="100%" cellpadding="0" cellspacing="0" class="news">
		<?php 
			$index = 1;
			foreach ($last_blog_post as $post): 
				if(count($last_blog_post) == $index) $class = 'class="last"';
				else $class = '';
//print_r($post);
		?>
			  <tr <?php echo $class; ?>>
			  	<?php 
			  		$chars = 35;
			  		if(strlen($post->title) > $chars) $post->title = substr($post->title,0,$chars).'...';
			  	?>
			    <th><h3 style="width: 170px;height: 55px;"><a href="<?php echo url('node/'.$post->nid);?>"><?php echo $post->title; ?></a></h3><span><?php echo date('j F Y',$post->created); ?></span></th>
			    <?php 
			  		$chars = 350;
			  		if(strlen($post->body) > $chars) $post->body = substr($post->body,0,strpos($post->body,' ',$chars)).'...';
			  	?>
			    <td>
			    	<p><?php echo strip_tags($post->teaser,'<b><a><strong>'); ?></p>
			    	<a href="<?php echo url('node/'.$post->nid);?>" class="blink">Read more</a>
			    </td>
			  </tr>
		 <?php 
		 		$index++;
		 	endforeach; 
		 ?> 
		</table>
</div>
