[Plugin: Simple Pie] adding custom field to array

Hi!

i’m havig this:

<?php echo SimplePieWP(array(
'https://gdata.youtube.com/feeds/base/videos?q=<strong>fifa10</strong>%r&client=ytapi-youtube-search&alt=rss&v=2'
),array('items' => '1')); ?>

How can I replace “fifa10” with the value of a custom field, in this case: “name”?

<?php echo c2c_get_custom('name'); ?>

(I’m using a custom fields plugin)
