I want the page below to drag from the certain category. I am unsure how to get it done...quite simply once the page is drawn up it'll pull all of the posts in one category which category only.

Unsure things to add or where you can add it? The course is "Available"


 *  Template Name: For Sale
 * @package WordPress
 * @subpackage Twenty_Ten
 * @since Twenty Ten 1.0

get_header(); ?>

    <div id="container">
    <div class="left_sirebar">
        <?php get_sidebar(); ?>
        <div id="content" role="main">
            <?php $args = array(  'posts_per_page' => 3 );
                        $loop = new WP_Query( $args );
                        while ( $loop->have_posts() ) : $loop->the_post();

                        if ($count==1)
                            echo "<tr>";

                       echo '<td><div class="For Sale">';
                        echo '<div class="heading_div"><h2 class="entry-title">';
                            echo '</div></h2>';
                        echo '<div class="entry-content">';

                            echo '<div class="desc">';
                        echo '</div>';
                    echo '</div></div></td>';

                        echo "</tr>"; 


        </div><!-- #content -->
    </div><!-- #container -->

You have to add the course title for your arguments array:

$args = array('posts_per_page' => 3, 'category_name' => 'For Sale');

WordPress' documentation is very good - whenever you need assistance having a function like Wordpress_Query, look up. Your solution was immediately within the documentation: All Posts in a Category.
