Displaying a single page

Is there a way to set up a link so that only one page is displayed? I have a link like this:

/?page_id=Contact”>Contact

When the page is displayed with page.php in the Them that I’m using all the pages are displayed, not just Contact. I want just contact to display.

The code in in page.php is as follows:

<?php get_header(); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_content(”); ?>
<?php link_pages(‘Pages: ‘, ”, ‘number’); ?>
<?php endwhile; endif; ?>
<?php get_footer(); ?>
