empty left sidebar in 3 column theme

Hi – just getting started – I’ve installed on a shared hosting environment and trying out different themes. I found one I like but not sure what to do – it’s telling me “Please enable widgets or modify leftbar.php to add content to this sidebar.”

Well, I don’t have “enable widgets” – and, in the Dashboard provided from the host. The code in that file looks like this:

<div id=”leftbar” class=”fixheight”>
<div id=”lb_t” class=”fixheight”>
<div id=”lb_r” class=”fixheight”>
<div id=”lb_b” class=”fixheight”>
<div id=”lb_l” class=”fixheight”>
<div id=”lbtl” class=”fixheight”>
<div id=”lbtr” class=”fixheight”>
<div id=”lbbr” class=”fixheight”>
<div id=”lbbl” class=”fixheight”>
<div id=”lb_c” class=”fixheight”>

<?php if ( function_exists(‘dynamic_sidebar’) && dynamic_sidebar(2) ) : else : ?>
• Please enable widgets or modify leftbar.php to add content to this sidebar.

<?php endif; ?>

</div></div></div></div></div></div></div></div></div></div> <?php /* sidebar */ ?>

I actually like this theme a lot but being new, I’m not sure what type things I can enter here. All the basics seem to be available in the main area or the right sidebar. Please help me understand what to do and what some possibilites are
