Cant adjust # of recent posts on front page of mimbo site

So I’m trying to increase the # of recents posts on blog.jeaneb.com

I’m adjusting this code

<div id="more-posts">
		<h3><?php _e('Recent Posts','Mimbo'); ?></h3>

		<?php
		}
		elseif( $postcount > 0 && $postcount <= 4 ) {
		//GETS NEXT FOUR EXCERPTS
		?>

and I should just have to change the 4 to an 8 but its not working

Any thoughts?
