Dyslexic experience

I've just been working on a code bug that's taken probably 30 minutes to resolve. I finally tracked it down but even when I used tools to help me pinpoint it it still wasn't obvious. I've been programming on and off for twenty years and have, naturally, developed the ability to pick out these kinds of things at 30yds. I've generally found the notion that you can look at two things and not see the difference or not be able to instantly see that "independant" is spelt wrong as particularly odd. So I guess this experience was an insight into that condition. Yikes.

See if you can spot the bug! The issue is that headlines are being repeated.

[% MACRO show_newspoints(nps, co, show_little) BLOCK %]
<ul>
[% count = 0; FOREACH np = nps %]
 [% IF np.headline != last_headine %]
<li>[% format_date(np.date) %] - [% np.publication %]: <strong>[% np.headline %]</strong>
 [% END %]
 [% IF np.synopsis %]
 <br />
  [%+ np.synopsis %]
 [% END %]
 [% IF cgi.param('debug') %]
Importance: [% np.importance %]</br />
Sentiment: [% np.sentiment %]<br/>
Subject: [% np.subject %]<br/>
Subject UID: [% np.subject_uid %]<br/>
 [%+ END %]
</li>
 [%+ count = count + 1 %]
 [% last_headline = np.headline %]
[%+ END %]
[% IF count == 0 AND show_little %]
<li>There was little coverage for [% co.name %] in the sources
reviewed in this period.</li>
[% END %]
</ul>
[% END %]
