Content custom on repeaters

So i have a reviews.php page with a content region of

<?php perch_content('Reviews'); ?>

And i wish to RAND call 3 from the field_id of datePublished to the index.php

<?php perch_content_custom('Reviews', array(
        'page'=>'/reviews.php',
        'template'=>'reviews-featured.html',
        'sort'=>'review.datePublished',
        'sort-order'=>'RAND',
        'count'=>3
    )); 
?> 

my repeater id is

<perch:repeater id="review" label="Review">

no output

Ok let me amend, the output is in fact fine but not restricted to a count of 3. Debug below. cheers for the help.

Oh i see, i wrapped the whole lot in a repeater, so could just add another easy, but maybe thats not the best way then. You can only count on the content not the repeater. as my content is all in the repeater its not seen then.

cheers for the help on this drew.

All sorted now I've taken it out the repeater.
