Issue when manually configuring sharethis

i am manually trying to use this plugin on my site, and no matter how i configure it i can not get sharethis to work.

if i use the code below on my site i have no issues

<?php echo wp_socializer(socialbts, array(
'effect' => 'jump',
'label' => '1',
'services' => 'facebook,twitter,pinterest,googleplus,addtofavorites,email'
));
?>

but when i try to use the following code

<?php echo wp_socializer(sharethis, array(
'output' => 'hcount',
'services' => 'facebook,twitter,pinterest,googleplus,addtofavorites,email'
));
?>

nothing shows up

am i doing something wrong?
