I'm trying to display a menu based on the page template AND the post category is used. I got it to work for the page template like this:

if (is_page_template('page-template-heroes.php')){ 
                        $primaryNav = wp_nav_menu( array( 'menu' => 'heroes', 'theme_location' => 'primary-menu', 'container' => '', 'fallback_cb' => '', 'menu_class' => $menuClass, 'menu_id' => 'top-menu', 'echo' => false ) ); 

But when I try it for a page template AND category, it's not working. Must be doing something wrong.

if (is_page_template('page-template-heroes.php') && in_category( 'skills-heroes' ) ){ 
                        $primaryNav = wp_nav_menu( array( 'menu' => 'heroes', 'theme_location' => 'primary-menu', 'container' => '', 'fallback_cb' => '', 'menu_class' => $menuClass, 'menu_id' => 'top-menu', 'echo' => false ) );
