Very unexpected T_STRING error

So I’m trying to use is_home() in a simple if/then statement, and suddenly I’m getting this error:


Parse error: parse error, unexpected T_STRING in /home/username/public_html/wordpress/wp-content/themes/awarmgun/structure/primary_navigation.php on line 5


Here’s the contents of primary_navigation.php:


<dl>
<dt id="home"<? if(is_home()) echo(" class=\"currentpage\">Home</dt>"); else echo("><a href=\"/\"
title=\"The front page — where you’ll find the most recently posted stuff\">Home</a></dt>"); ?>
<dd>The front page — where you’ll find the most recently posted stuff</dd>
<dt id="archives"<? if(is_page('archives')) echo(" class=\"currentpage\">); ?><a href="/archives/" title="The archives — older articles, listed by date">Archives</a></dt>
<dd>The archives — older articles, listed by date</dd>
<dt id="linkblog"<? if(is_page('linkblog')) echo(" class=\"currentpage\">); ?><a href=\"/linkblog/\" title=\"The Link Blog — an (almost) daily list of interesting links\">Link Blog</a></dt>
<dd>The Link Blog — an (almost) daily list of interesting links</dd>
</dl>

I’ve been wracking my brain trying to figure out what’s wrong with it, but as far as I can tell, there’s nothing wrong with it at all. Maybe I just need a set of fresh eyes?

Thanks!
