Hide div element from index.php

Hi all,

I’m trying to hide a specific code that is essential to my post, but that I don’t want showing up on in the index.php.

Here’s the specific div element as it shows in the page source (with the text edited):

<div class="greet_block">
<div class="greet_text">hi
<div style="clear:both"></div></div></div>

In the past I was able to hide image captions using this code in the header:

<?php if ( is_home() )
	add_filter('img_caption_shortcode', create_function('$a, $b, $c',
'return $c;'), 10, 3); ?>

Unfortunately, that code doesn’t work when I try to replace “img_caption_shortcode” with “greet_block”.

Any help?
