The shortcode in PHP doesnt work

Hey, the result you see at the link:
https://skkelti.cz/index1/
My code:

<?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.

get_header(); ?>

		<div id="primary" class="content-area">
			<div id="content" class="site-content" role="main">
                            </p
			<?php 
                        echo do_shortcode( '[recent_post_slider design="design-3" show_category_name=“false“]
' );
                        
                        
                        if ( have_posts() ) : ?>

				
				<?php /* Start the Loop */ ?>
				<?php while ( have_posts() ) : the_post(); ?>

					<?php
						/* Include the Post-Format-specific template for the content.
						 * If you want to overload this in a child theme then include a file
						 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
						 */
						get_template_part( 'content', get_post_format() );
					?>

				<?php endwhile; ?>

				<?php sporty_content_nav( 'nav-below' ); ?>

			<?php else : ?>

				<?php get_template_part( 'no-results', 'index' ); ?>

			<?php endif; ?>

			</div><!-- #content .site-content -->
		</div><!-- #primary .content-area -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
