My self hosted WP blog has 2 sidebars. One left, one right, and content in center.

I would like to keep this setup on the homepage but eliminate the right sidebar from other pages.

I am not too familiar with PHP and am not sure which file needs to be changed.

Any help would be greatly appreciated.

Go to your themes map and go to sidebar.php copy it to here

PHP Code:

<!-- begin sidebar -->
        <div id="sidebar">
                <?php     /* Widgetized sidebar, if you have the plugin installed. */
                    if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar("Sidebar One") ) : ?>
                    <div class="side-widget">
                        <?php include 'searchform.php'; ?>
                    </div>                
                    <div class="side-widget">
                           <?php _e('<h2>Links</h2>', "magazine-basic"); ?>
                            <ul>
                            <?php wp_list_bookmarks('title_li=&categorize=0'); ?>
                            </ul>
                    </div>
                    <div class="side-widget">
                           <?php _e('<h2>Calendar</h2>', "magazine-basic"); ?>
                                <?php get_calendar(); ?>
                    </div>
                    <div class="side-widget">
                           <?php _e('<h2>Archives</h2>', "magazine-basic"); ?>
                            <ul>
                                <?php wp_get_archives('type=monthly'); ?>
                            </ul>
                    </div>
                    <div class="side-widget">
                           <?php _e('<h2>Tags</h2>', "magazine-basic"); ?>
                                <?php wp_tag_cloud(); ?>
                    </div>
                  <?php endif; ?>
        </div>
<!-- end sidebar -->
