share this button with counter how to put it ?

hello,

I'm quite confused about this plugin share this, as I don't succeed to activate properly, and it's driving me crazy !

so i wish to integrate the horizontal counter at the end of the body of each post.

on the plugin page :
http://www.sharethis.com/publishers/...n-code?style=6

they give 2 codes and say that i should paste the second
<script type="text/javascript" src="http://w.sharethis.com/button/buttons.js"></script><script type="text/javascript">stLight.options({publisher:'a5193365-3865-4c43-a497-4feda5851601'});</script>

at the end of my header html inserts
but of course i get the buttons in the header and i don't want them in there.

where should i paste it ? i don't neither want the button in the footer of my posts, but at the bottom of the body.

and what about the first code (the button code) :
<span class="st_twitter_hcount" displayText="Tweet"></span><span class="st_facebook_hcount" displayText="Share"></span><span class="st_email_hcount" displayText="Email"></span><span class="st_sharethis_hcount" displayText="Share"></span>
when i paste it in the sharethis option page and then I register the pasting, the code disappear, so i can't change it or remove it, i have to erase the plugin in order to refresh it... !

am i stupid or what ? ^^
can you help me ?
