Menu is not working

I moved the menu to the top of the header but there is no functionality.
I can change the order of menu items but nothing happens when you hover over them.
I cut and pasted the content about the nav bar in my header “<nav id=”site-navigation” class=”navigation-main” role=”navigation”>
<h1 class=”menu-toggle”><?php _e( ‘Menu’, ‘expound’ ); ?></h1>
<div class=”screen-reader-text skip-link”>“><?php _e( ‘Skip to content’, ‘expound’ ); ?></div>
<?php wp_nav_menu( array( ‘theme_location’ => ‘primary’, ‘depth’ => 3 ) ); ?>
<?php do_action( ‘expound_navigation_after’ ); ?>
</nav><!– #site-navigation –>” so maybe there is something that got dropped?
