multiple sidebars problem

Basically I tried to setup separate sidebars for specific pages on a site. In the widgets cp I see the sidebars listed and can add widgets which then appear on the page. However when I return to the widgets cp all of the widgets are gone from the sidebars. Here’s the code I used:

functions.php

if ( function_exists('register_sidebar') ) {
	register_sidebar( array(
        'name' => ('Main Sidebar'),
        'id' => 'sidebarMain',
        'description' =>  ('Main site sidebar (default'),
        'before_widget' => '',
        'after_widget' => '',
        'before_title' => '',
        'after_title' => ''
    ) );
	register_sidebar( array(
        'name' => ('Homepage Sidebar'),
        'id' => 'sidebarHomepage',
        'description' => ('Use to create 3 column layout on homepage.'),
        'before_widget' => '<div class="hpColumn %1$s">',
        'after_widget' => '</div>',
        'before_title' => '<h2>',
        'after_title' => '</h2>'
    ) );
	register_sidebar( array(
        'name' => ('Contact Sidebar'),
        'id' => 'sidebarContact',
        'description' => ('Use for contact form.'),
        'before_widget' => '',
        'after_widget' => '',
        'before_title' => '',
        'after_title' => ''
    ) );
	register_sidebar( array(
        'name' => ('Blog Sidebar'),
        'id' => 'sidebarBlog',
        'description' => ('Use for contact blog.'),
        'before_widget' => '',
        'after_widget' => '',
        'before_title' => '',
        'after_title' => ''
    ) );

}

On a specific template page (contact) I have:
get_sidebar( 'contact' );

and then have
sidebar-contact.php

<?php 	/* Widgetized sidebar, if you have the plugin installed. */
					if ( function_exists('dynamic_sidebar') || dynamic_sidebar('Contact Sidebar') ) : ?>
			<?php endif; ?>

Any help would be appreciated.
