Hi @davidjustin

This will be possible, but lets first forget about the AJAX side. Lets make it a bit more basic:

1. The user selects a post type
2. The user saves the post
3. The user sees the select field populated with repeater values from the post type selected

<?php 

function my_acf_load_field( $field )
{
	// globals
	global $post;
	
	
	// load selected value from post type field
	$p = get_field( 'Field_B', $post->ID );
	
	
	// now load repeater field from selected post object
	if(get_field( 'Field_B', $p->ID ))
	{
		// loop through the repeater and use the sub fields "value" and "label"
		while(has_sub_field('Field_B', $p->ID))
		{
			$value = get_sub_field('value');
			$label = get_sub_field('label');
 
			$field['choices'][ $value ] = $label;
		}
	}
	
    return $field;
}

// acf/load_field/name={$field_name} - filter for a specific field based on it's name
add_filter('acf/load_field/name=Field_A', 'my_acf_load_field');

 ?>

This is untested but should work. After you have it working, you can write some AJAX to fetch the values.
