Can't get widget to work properly

I am using Random One Cat widget to display testimonials at random on my site. It’s displaying random posts from any category and not the specific “quotes” category. I tried displaying a different post category, and it works, but not for the one I want.

Functions:

register_sidebar(array(
‘name’=>’Quotes’,
‘before_widget’ => ‘<div id=”%1$s” class=”widget %2$s”>’,
‘after_widget’ => ‘</div>’,
‘before_title’ => ‘<h3 class=”mast”>’,
‘after_title’ => ‘</h3>’,
));

Template:

<?php if ( !function_exists(‘dynamic_sidebar’)
|| !dynamic_sidebar(‘Quotes’) ) : ?>

<?php endif; ?>

Why won’t it let me display my new post category “Quotes”? Thanks!
