Help with menu tabs

[Gummo]

I've made a new menu tab, pointing to a news page. However, when at the news page the Home button is highlighted, rather than the News button. Is there a simple way to fix this? Please help.

Here is the code, in index.template.php:

if ($context['current_action'] == 'news')
$current_action = 'news';

And here is the second part:

// Show the [news] button.
echo ($current_action=='news' || $context['browser']['is_ie4']) ? '<td class="maintab_active_' . $first . '">&nbsp;</td>' : '' , '
<td valign="top" class="maintab_' , $current_action == 'news' ? 'active_back' : 'back' , '">
<a href="http://10.16.196.15/index.php">news/index</a>
</td>' , $current_action == 'news' ? '<td class="maintab_active_' . $last . '">&nbsp;</td>' : '';
