re: I am trying to add a custom field using the tile-plus template.

What custom field? One that you coded from scratch or to display the text of a Custom Field from the metbox when you add a new entry?

re: I have installed snippet and was able to get the field to show in the admin section

Which snippet? I give allot of those out in the forums.

re: Everytime I enter the code from the quick fix into the card.php file it just shows the text of the code.

If you are seeing the text of the, then you are not pasting the code in between the opening and closing php tags (<?php and ?>).
