Can't print fields in a view template
The template you have overwritten looks like this (in Drupal 6):

&lt;?php if (!empty($title)): ?&gt;
  &lt;h3&gt;&lt;?php print $title; ?&gt;&lt;/h3&gt;
&lt;?php endif; ?&gt;
&lt;?php foreach ($rows as $id =&gt; $row): ?&gt;
  &lt;div class="&lt;?php print $classes[$id]; ?&gt;"&gt;
    &lt;?php print $row; ?&gt;
  &lt;/div&gt;
&lt;?php endforeach; ?&gt;


As you can see, it's purely used to print out the rows in the view; you should instead use one of the other templates available, if you want to alter the fields. Take a look at the theming information button in the UI that will give you a complete list with previews.
