Custom widget remember multiple select options (3 posts)

    I'm writing a custom widget for our site to display some chosen posts. In the admin part, I've got a multiple select box to let the admin choose multiple posts by their name. This is working fine, but when I select a few different posts and save, nothing is getting saved.

    Can anyone shed any light on this?

    Here is my code…

    <?php
    /*

    class HotTopics extends WP_Widget {
    
    	// constructor
    	function HotTopics() {
    		$widget_ops = array( 'name' => 'Hot Topics','classname' => 'widget-hot-topics', 'description' => __( "Use this widget to choose an array of posts snippets to show in the sidebar." ) );
    		$this->WP_Widget( 'hottopics', __('Hot Topics'), $widget_ops);
    	}
    
    	// widget form creation
    	function form($instance) {
    		// Check values
    		if( $instance) {
    			$select = esc_attr($instance['select']); // Added
    		} else {
    			 $select ='';
    		}
    		?>
    
    		<select multiple="multiple" name="<?php echo $this->get_field_name('select'); ?>[]" id="<?php echo $this->get_field_id('select'); ?>" class="widefat" size="15" style="margin-bottom:15px;">
    			<?php
    			$args = array( 'offset'=> 1, 'orderby' => 'date', 'order' => 'DESC', 'posts_per_page' => 200, 'post_status' => 'publish' );
    
    			// The Query
    			query_posts( $args );
    
    			// The Loop
    			while ( have_posts() ) : the_post();
    
    			$title = get_the_title();
    			?>
    				<option value="<?php echo get_the_ID();?>" class="hot-topic" <?php $select == $title ? ' selected="selected"' : '';?> style="margin-bottom:3px;">
    			    	<?php echo $title;?>
    			    </option>
    				<?php
    			endwhile;
    
    			// Reset Query
    			wp_reset_query();
    			?>
    		</select>
    
    		<?php
    	}
    
    	// update widget
    	function update($new_instance, $old_instance) {
    	      $instance = $old_instance;
    	      // Fields
    	      $instance['select'] = strip_tags($new_instance['select']);
    	     return $instance;
    	}
    
    	// widget display
    	function widget($args, $instance) {
    		/* ... */
    		echo 'tetst';
    	}
    }
    
    // register widget
    add_action('widgets_init', create_function('', 'return register_widget("HotTopics");'));
    
    ?>
