I’m still not really sure I’m understanding what you mean. Tell if this is correct.
1) You have a single post of some kind. For this post you have taxonomy set up and you select a term in this taxonomy for your post. Do you want to show a custom field from this term?
2) You have a post with a Taxonomy Field and you want to show the name of the Term selected in this field.
Something else? Sorry, I’m just not getting the relationship between the post and what you want to display.
