WordPress- Calling a function - not working when using custom tag

Question

The following function works by adding it to >the_content() , however, I want to display it at a custom location in my html markup via a custom tag, when I tried this I got a PHP error, I'm sure this is something very simple but I for the life of me cannot see the issue.

  // code from crunchify
 function supersun_social_sharing_buttons($content) {
    global $post;
    if(is_singular() || is_home()){

        // Get current page URL
        $supersunURL = urlencode(get_permalink());

        // Get current page title
        $supersunTitle = str_replace( ' ', '%20', get_the_title());

        // Get Post Thumbnail for pinterest
        $supersunThumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );

        // Construct sharing URL without using any script
        $twitterURL = 'https://twitter.com/intent/tweet?text='.$supersunTitle.'&url='.$supersunURL.'&via=Crunchify';
        $facebookURL = 'https://www.facebook.com/sharer/sharer.php?u='.$supersunURL;
        $googleURL = 'https://plus.google.com/share?url='.$supersunURL;
        $whatsappURL = 'whatsapp://send?text='.$supersunTitle . ' ' . $supersunURL;
        $pinterestURL = 'https://pinterest.com/pin/create/button/?url='.$supersunURL.'&media='.$supersunThumbnail[0].'&description='.$supersunTitle;

        // Add sharing button at the end of page/page content
        $variable .= '<div class="supersun-social">';
        $variable .= '<a class="supersun-social-link supersun-twitter" href="'. $twitterURL .'" target="_blank" title="Share on Twitter"><i class="fa fa-twitter" aria-hidden="true"></i></a>';
        $variable .= '<a class="supersun-social-link supersun-facebook" href="'.$facebookURL.'" target="_blank" title="Share on Facebook"><i class="fa fa-facebook" aria-hidden="true"></i></a>';
        $variable .= '<a class="supersun-social-link supersun-whatsapp" href="'.$whatsappURL.'" target="_blank" title="Share on Whatsapp"><i class="fa fa-whatsapp" aria-hidden="true"></i></a>';
        $variable .= '<a class="supersun-social-link supersun-googleplus" href="'.$googleURL.'" target="_blank" title="Share on Google+"><i class="fa fa-google-plus" aria-hidden="true"></i></a>';
        $variable .= '<a class="supersun-social-link supersun-pinterest" href="'.$pinterestURL.'" target="_blank" title="Share on Pinterest"><i class="fa fa-pinterest" aria-hidden="true"></i></a>';
        $variable .= '</div>';

        return $variable.$content;
    }else{
        // if not a post/page then don't include sharing button
        return $variable.$content;
    }
};
add_filter( 'the_content', 'supersun_social_sharing_buttons');

THIS ERROR MESSAGE APPEARS WHEN I ADD <?php supersun_social_sharing_buttons(); ?> <?php supersun_social_sharing_buttons(); ?> TO MY THEME.

Thank you so much for your time. Sorry the site is not currently live, I think this should be an easy fix for someone with an experienced eye.

You need pass a parameter when you call your function directly, not in add_filter . Like this <?php supersun_social_sharing_buttons($parameter); ?> <?php supersun_social_sharing_buttons($parameter); ?>
