How do I set a File field from the acf api?

I have a repeater field group set up with the following sub fields

1. accessory_name – type=text
2. accessory_file – type=file
3. accessory_description – type=Wysiwyg Editor

I am creating posts that use this repeater group and I am able to set values into both the sub accessory_name and accessory_description fields just fine, but when I try to add a filename to the accessory_file I can see when I am in my code debugger that I have assigned a filename string to the sub_field, but when I edit the post in WordPress the field shows as empty.

Just to explain how the files are added:-
In the process of creating the post I upload files for each of the accessories (pdf’s, mp3’s, jpg’s etc) and rename them into wp_upload_dir(). I then create an attachment post. This is done as follows:

                if (rename($from, $to)) {
                // If the rename worked then create an attachment for it and make the parent the collection post
                // Prepare an array of post data for the attachment.
                // Check the type of file. We'll use this as the 'post_mime_type'.
                $filetype = wp_check_filetype( $file['name'], null );
                $post_title = preg_replace( '/\.[^.]+$/', '', $file['name'] );
                $attachment_params = array(
                    'guid'           => $wp_upload_dir_info['url'] . '/' . $file['name'],
                    'post_mime_type' => $filetype['type'],
                    'post_title'     => $post_title,
                    'post_content'   => '',
                    'post_status'    => 'inherit'
                );
I have a repeater field group set up with the following sub fields 
<ol>
	<li>accessory_name - type=text</li>
	<li>accessory_file - type=file</li>
	<li>accessory_description - type=Wysiwyg Editor</li> 
</ol>

$filetype = wp_check_filetype( $file[‘name’], null );
$post_title = preg_replace( ‘/\.[^.]+$/’, ”, $file[‘name’] );
$attachment_params = array(
‘guid’ => $wp_upload_dir_info[‘url’] . ‘/’ . $file[‘name’],
‘post_mime_type’ => $filetype[‘type’],
‘post_title’ => $post_title,
‘post_content’ => ”,
‘post_status’ => ‘inherit’
);
add_row(‘nh_book_accessory’, $row, $postID);

I then add the value to the accessory_file like this:

$row = array(
‘attachment_post_id’ => $attachID,
‘accessory_name’ => $post_title,
‘accessory_file’ => $file[‘name’],
‘accessory_description’ => $accessory_description
);
add_row(‘nh_book_accessory’, $row, $postID);

Can anyone tell me what I am doing wrong, or maybe what I'm missing.

Possibly I should be putting the attachment guid in this field? T think the documentation for setting a file type 'file' could do with having some info on this.

Thanks,

The file field must hold the attachment ID for the attachment that you inserted.
