Archive Template

Hi,

My current archives template looks like this http://www.gavinlikesdesign.com/wp/2010/08/

However, for some reason I can’t get the summary to show instead of the entire post.

I have inserted this code:

<?php the_content("There's more to this story...") ?>

An example of what I need the posts to look like is on this page: http://www.gavinlikesdesign.com/wp/2010/08/

The code on my Archives template is pretty much the exact same as what is on the above template.

Any help would be appreciated.
