fouldsy99 on "Single.php"

On my single.php I have a floating share bar of facebook, twitter etc. The facebook button has like but I would rather the feature be share.

How can I change this?

Here's the code I currently use:

<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo urlencode(get_permalink($post->ID)); ?>&layout=button_count&show_faces=false&width=100&action=like&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:100px; height:20px;"></iframe>

Any help appreciated.
