How to display data from custom fields I created?

I think you want to look into using get_post_meta and then display it with that. Here it is on the Codex: http://codex.wordpress.org/Function_Reference/get_post_meta

You can look at this example:

<?php
echo get_post_meta($post->ID, $prefix.'where', true);
?>

That should get you what you need if I understand the question correctly.
