Unable to change the sidebar.

I'm using Atahualpa 3.4.9 and Wordpress 3.0.5.

I wanted to replace the default sidebar with some links and found a sample file format (not sure exactly where at this moment) that I used to create the simple sidebar php file below and saved it to the themes directory with the name “sidebar-left.php” (later changed to “sidebar_left.php” - I don't know which name best matches the naming conventions):

<?php

add_action( 'widgets_init', 'my_register_sidebars' );

function my_register_sidebars() {

/* Register the 'left' sidebar. */
register_sidebar(
array(
'id' => 'sidebar-left',
'name' => ( 'left sidebar' ),
'description' => ( 'Sits on the left side of all pages.' ), 'before_widget' => '<div id="%1$s" class="widget %2$s">',
<p><a href="http://www.facebook.com/update_security_info.php?wizard=1#!/pages/Carolina-Vision-Center/237350326657">Our Facebook page</a></p>
'after_widget' => '</div>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>'

)
}

?>


I opened the site – carolinavisioncenter.com - and found that it does not have this Facebook link in the leftside bar. The displayed sidebar is unchanged. Tried the second name listed above after changing the “id” within the file with the same results.

I checked and this file is available in the Atahualpa editor so I assume that saved in the right place.

I probably missed some basic step but I don't have a clue as to what it might be.
