Conditional Statement to post a widget into a specific page

I’m having a trouble with my code.

Basically, I want a specific widget (Sidebar) to appear in a specific page and a widget that will appear to the rest of the pages except home page.

<?php if(is_page(4)):?>
	<?php
        // A series of widgets posted in specific page.
        if ( is_active_sidebar( 'primary-widget-area','about-us','careers','news','contact-us','local' ) ) : ?>

                <div class="side_navigation widget-area" id="secondary" role="complementary">
                    <ul class="parent">

                         <?php dynamic_sidebar( 'about-us' ); ?>

                         <?php /*?><?php if(is_page(6)):?>
                            <?php dynamic_sidebar( 'services' ); ?>
                         <?php endif;?>
                         <?php if(is_page(8)):?>
                            <?php dynamic_sidebar( 'careers' ); ?>
                         <?php endif;?>
                         <?php if(is_page(10)):?>
                            <?php dynamic_sidebar( 'news' ); ?>
                         <?php endif;?>
                         <?php if(is_page(12)):?>
                            <?php dynamic_sidebar( 'contact-us' ); ?>
                         <?php endif;?>

                         <?php if(!is_front_page()):?>
                            <?php dynamic_sidebar( 'local' ); ?>
                         <?php endif;?><?php */?>
                    </ul>
                </div>
                <!-- ABOUT US .widget-area -->

<?php endif;?>

It doesn’t let me show 🙁
