Go To Edit HTML section and click the “Expand Widget Templates” check box.
Now press Crt+F and search for this specific line of code

<data:post.body/>

Right after this line add this code:

<div style='float:left;'>
<script type='text/javascript'>submit_url = ‘data:post.link/]’;</script>
<script src='http://sphinn.com/evb/button.php' type='text/javascript'/> </div>

Now save your template.
Thats it.
