does not show up

I am trying to get some rich snipped code on my wordpress site, but I
can´t get it to work. I have got several articles that are reviews, so my
aim is to add some micro data for itemtype="http://schema.org/Review". You
can check this article for testing and see how the code shows up on the
internet browser. Notice that the bit missing on the browser is .
This is the code I have on my theme sigle_post.php file:
<!-- review box -->
<div class="reviewbox">
<div itemscope="itemscope"
itemtype="http://schema.org/Review">
<!-- Este es el nuevo título para las reviews -->

get_post_custom_values('reviewauthorthemeloy_text');

get_post_custom_values($rate_value);
