Interesting, I'm getting the famous array reference error with that
code(first line below):
<?php $top = array_splice(0,$tags2show,$tags); ?>
<?php shuffle($top); ?>

Fatal Error: Only variables can be passed by reference...

The fix should be to store function array results in a temp variable
but I don't see where I'm not doing that?
