Adding a Price

Hey Chriz122,

Does the text "Preis:" show up?

If so, then one possible issue I think could occur is with the get_field() call. By default get_field() returns the field value for the current page / post. In the case of a page containing the blog module this might cause it to return the price value set on the page itself (which is probably not set), rather than picking it up from the posts listed in the blog module. ACF might pick up the correct posts from the blog module loop - I'm not sure off the top of my head - but if not you may need to pass the post id as the second parameter to get_field() - something like this:

$price = get_field('price', $post_id);

(you'd need to set $post_id in your code).
