Streamline Widget Management

[Lean Agile Teams]

I installed twitter widget "twitter goodies" site: http://arpitshah.com/plugins/twitter-goodies/
and am able to place into the Streamline with drag and drop.

However, the drag and drop process overladed what was in the left sidebar (categories and archives). So I created a new list item (www.projectpmi.com) and inserted the "<!–wp_twitter_goodies–>" statement as instructed below from twitter goodies website.

Unfortunately, nothing happened other than I was successful at creating another "sidebar box". I realize that I do not understand the function this is trying to perform - a call perhaps.

Instructions from website"
1) Add both widgets into sidebar – Go to Appearance -> Widgets -> Twitter Goodies
2) <!–wp_twitter_goodies–> – to add Twitter Goodies Profile widget on page/post
3) <!–wp_twitter_goodies_search–> – to add Twitter Goodies Search Widget on page/post
4) Twitter Integration: Activate integration option from Admin Panel

A snippet from my last below:

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

<li id="categories" class="widget">
<h4><?php _e("Categories", 'studiopress'); ?></h4>
<ul>
<?php wp_list_categories('orderby=name&title_li=&depth=2 '); ?>
</ul>
</li>

<li id="archives" class="widget">
<h4><?php _e("Archives", 'studiopress'); ?></h4>
<ul>
<?php wp_get_archives('type=monthly'); ?>
</ul>

<li id="twitter" class="widget">
<h4><?php _e("Twitter", 'studiopress'); ?></h4>
<ul>
<!–wp_twitter_goodies–>
</ul>


<?php endif; ?>
