Breadcrumbs - how to add pages to navigation

I cant seem to add the post page to the navigation. Can I send you a screen shot of how I've tried to add it as I must have done something wrong.

My problem in summary :

I can get <?php perch_pages_breadcrumbs(); ?> to work when it is in a page within my menu - eg my news page.

However, I cant get it to show on my post.php pages.

Post.php is called from 3 pages within the site (agenda, minutes and planning). The blog posts display ok, but the breadcrumbs dont. You suggest adding the post.php as a subpage - so I have added it under planning as a subpage but that doesnt make any difference. (Location path ../blog/post.php, parent page : planning, master : default, etc

The code is below, but when i check the code for post.php in source view, the breadcrumbs is missing (it shows fine under my news.php page).

<div id="page-column-wide"> <?php perch_pages_breadcrumbs(); ?> <?php perch_blog_post(perch_get('s')); ?> </div>

Many thanks

Does this help?

Ok, so my problem is that i need to add some way for the user to navigate back to the blog list of posts from within a post. I wanted to use breadcrumbs, but breadcrumbs dont show up from within a post and there doesnt seem to be a reason (nothing untoward). So is there anyway I can do it?
