Styling header text on pages

I think I'm suffering from code overload, and missing an obvious fix here.

I would like to style, or more specifically, underline the header text on pages. Here's the source code. My goal is to underline "Compliance Auditing" in line 3. Any advice? Thanks in advance!

<div class="page" id="blog-page">
<h2 class="pagetitle">Compliance Auditing</h2>
<div class="post" id="post-16">
<div class="entry">
