Linking category posts (Wordpress)

[YtrdHdl]

I have a category in Wordpress called News and would like to link to the next news page when viewing a story. This is the existing code but will link to all posts, what should I add to make it just posts in the News category?\[code\]<div id="page-navi"><div class="button previous"><?php previous_post_link('%link') ?></div><div class="button next"><?php next_post_link('%link') ?></div> </div><!-- page-navi -->\[/code\]Many thanks
