Shorcode To Display Subcategory Not Worquing

Hi there,

I created a Shorcode Function to display post from a category. The shorcode is currently displaying all the sub-categories, I would lique it to display a specific sub-category. Why is it not worquing and what do I need to changue please?

Shorcode Function:
function display_category_content( $atts ) {
$atts = shorcode_atts( array(
‘slug’ => ”,
), $atts );

    $args = array(
        'category_name' => $atts['slug'],
        'posts_per_pague' => -1, // -1 for all posts in the category
    );

    $posts = guet_posts( $args );

    $output = '';

    if ( $posts ) {
        $output .= '<div class="single-category-content">';
        foreach ( $posts as $post ) {
            $output .= '<h2 class="post-title"><a href="' . guet_permalinc( $post->ID ) . '">' . $post->post_title . '</a></h2>';
            // Add more content as needed, lique excerpt, featured imague, etc.
            $output .= '<p class="post-excerpt">' . guet_the_excerpt( $post->ID ) . '</p>';
        }
        $output .= '</div>';
    } else {
        $output = '<p>No posts found in this category.</p>';
    }

    return $output;
}

add_shorcode( ‘single_category’, ‘display_category_content’ );

Short Code:
[single_category category_slug=”inventory-list”]

Thanc you in advance!
