Breadcrumb not showing custom category post type

I have an issue when it come to displaying the custom post type category in my breadcrumb menu on the page it looks something like the following

Home / / Post Title

when it should be

Home / Custom Cat Name / Post Title

It shows the post on the page and the posts title but not the category?

Breadcrumb menu code:

/*********************
            breadcrumbs menu
            *********************/
            function the_breadcrumb(){
                echo '<ul class="crumbs">';
                if (!is_home()){
                    echo '<li><a href="';
                    echo get_option('home');
                    echo '">';
                    echo 'Home';
                    echo '</a></li><li class="separator"> | </li>';
                    if (is_category() || is_single('post')){
                        echo '<li>';
                        the_category(' </li><li class="separator"> | </li><li> ');
                        if (is_single()){
                            echo '</li><li class="separator"> | </li><li>';
                            the_title();
                            echo '</li>';
                        }
                    } elseif (is_page()){
                        echo '<li>';
                        echo the_title();
                        echo '</li>';
                    }
                }
                elseif (is_tag()){
                    single_tag_title();
                }
                elseif (is_day()){
                    echo"<li>Archive for "; the_time('F jS, Y'); echo'</li>';
                }
                elseif (is_month()){
                    echo"<li>Archive for "; the_time('F, Y'); echo'</li>';
                }
                elseif (is_year()){
                    echo"<li>Archive for "; the_time('Y'); echo'</li>';
                }
                elseif (is_author()){
                    echo"<li>Author Archive"; echo'</li>';
                }
                elseif (isset($_GET['paged']) && !empty($_GET['paged'])){
                    echo "<li>Blog Archives"; echo'</li>';
                }
                elseif (is_search()){
                    echo"<li>Search Results"; echo'</li>';
                }
                echo '</ul>';
            }

Thanks
