Can't print breadcrumb
theme_breadcrumb() would probably be the best choice:

print theme('breadcrumb', array('breadcrumb' =&gt; $breadcrumb));


It expects the breadcrumb variable to be an array, each item of which makes up one part of the breadcrumb trail. So this array:

$breadcrumb[] = l('Home', '&lt;front&gt;');
$breadcrumb[] = l('Page', 'page');
$breadcrumb[] = l('Subpage', 'page/subpage');


will produce:

Home &gt; Page &gt; Subpage


You can also use plain text instead of links for the breadcrumb items in case you need to.
