Removing list titles from sidebar

Hello,

I’m desperately trying to find a way to remove the title above the list of pages in my sidebar.

For reference, the website is at http://www.c-bop.com

“Information” is the text I input in the Pages widget, and the links below are the pages. In other words, I would like to remove “Information” from the sidebar completely and just begin with “About us, Mission statement…” etc.

Is this possible? I have not been able to find an answer anywhere online.

I think this might be the relevant code from the sidebar.php (I’m using the GrayLines theme, btw…):

<?php wp_list_pages(‘depth=3&title_li=<h2>Pages</h2>’); ?>

I’ve tried all sorts of things, like removing everything inside the (), but to no avail. I must admit, I know nothing about PHP, so I hope someone might be able to offer some insight.

Many thanks in advance!
