Problem showing blog posts in Runway

Hello,

I'm having some trouble showing blog posts in Runway.

The posts are imported from Wordpress and I ned to use the slug from the current site: "/post/{post-title}"

I have in Post Page Options

URL pattern: post/[slug:s]

in Blog Settings

Blog post page path: /post/{postSlug}

Slug format: {postTitle}

and in post.php

$post_slug = 'post/'.perch_get('s'); 
perch_blog_post($post_slug);

Now when I go to a blog post it renders everything except the post itself, so 'perch_blog_post($post_slug);' returns nothing.

Could you please let me know what am I dong wrong?
