Admin Columns & Custom Post Types

Hi

I am trying to add custom columns to a custom post type of ‘character’.

I have managed to add 2x new columns but I can’t seem to echo out the thumbnail or text field from the custom post.

Can anyone tell me what’s wrong with my code please?

Note: My code is contained within a simple plugin.

function my_character_columns($columns)
{
	$columns = array(
		'cb'	 	=> '<input type="checkbox" />',
		'thumbnail'	=>	'Profile Picture',
		'title' 	=> 'Character Name',
		'subtitle' 	=> 'Character Sub Title',
	);
	return $columns;
}

function my_custom_character_columns($column)
{
	global $post;
	
	if($column == 'thumbnail')
	{
		echo wp_get_attachment_image( get_field('character_profile_picture', $post->ID), array(200,200) );
	}
	
	elseif($column == 'subtitle')
	{
		echo get_field('character_sub_title');
	}
	
}

add_action("manage_character_custom_column", "my_custom_character_columns");
add_filter("manage_edit-character_columns", "my_character_columns");

The hook for the function that shows the column content should be

add_action("manage_character_posts_custom_column",
    "my_custom_character_columns", 10, 2);

I also changed it to use 2 parameters because this hook will pass the post id and then you can remove you global statement.

function my_custom_character_columns($column, $post_id)
