How can put this button under "add to cart" bottun ?

PHP Code:
<?php if (UN_MODULE_WISHLISTS_ENABLED) { ?>
            <div id="productWishlistLink" class="buttonRow back">
            <?php echo zen_image_submit(UN_BUTTON_IMAGE_WISHLIST_ADD, UN_BUTTON_WISHLIST_ADD_ALT, 'name="wishlist" value="yes"'); 
            //print_r($_REQUEST);
            ?></div>
    
        <?php }
            else
            {}
            ?>

Thanks
