AddThis Positioning to title

Hi there,

I am using the AddThis WP Plug-In with the Twenty Ten theme. Now I’d like to position it to the title of each blog post. I figure I have to use the following code to recall the toolbar: <?php do_action( ‘addthis_widget’, get_permalink(), get_the_title()); ?>

When I place it in index.php the bar shows up. However, index.php seems not the be the right place, as each post is coded in loop.php

Yet, the bar doesn’t show up when i place the code in loop.php. Actually nothing shows up when I place it in loop.php

Which code do I have to use to place it in loop.php?

Thanks and cheers,
David
