AddThis

customising favorites button

Hi there,

We are struggling to customise the addthis tool correctly and are looking for some help.

We want to have one single tweet button and one single favorites button.

The tweet button works, but for some reason we can't get the favorites button to work.

This is what we've got:

<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style ">

<a class="addthis_button_twitter" href="http://www.addthis.com/bookmark.php">
<img src="tweet.gif"
border="0" alt="Share" /></a>

</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=xa-4f2681e62ef5ed77"></script>
<!-- AddThis Button END -->


<br />
<br />

<div class="addthis_toolbox addthis_default_style">

<a class="addthis_button_preferred_2">
<img src="specific.png"
border="0" alt="Share" /></a>

</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=xa-4f2681e62ef5ed77"></script>
<!-- AddThis Button END -->

Any help would be much appreciated!
