Dynamic Sidebar trouble

I am trying to get my sidebar to work, but it simply won’t. The code is pretty basic:
In my functions I have:

function padd_widgets_init() {
	register_sidebar(array(
		'name' => 'Sidebar',
		'before_widget' => '<div id="%1$s" class="box %2$s">',
		'after_widget' => '</div></div>',
		'before_title' => '<div class="title"><h3>',
		'after_title' => '</h3></div><div class="interior">',
	));
}
add_action('widgets_init','padd_widgets_init');

The sidebar.php file looks like this:

<div id="sidebar">
	<div class="pad">
		<h2>Sidebar</h2>

	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Sidebar') ) : ?>

	<?php endif; ?>

	</div>
</div>

And the page.php contains <?php get_sidebar(); ?> but I have also tried <?php get_sidebar('Sidebar'); ?> to no avail.

Am i doing something wrong?
