Fix this code for wordpress

I have a custom meta box carousel which I have working, The only problem im having is it is only looping through one picture, the same image is shown on the slides.Can someone please point me in the correct direction please.Thanks

$images = get_post_meta( $post->ID, '_agd_test_file_list', true );
if ( $images )
{ foreach ( $images as $attachment_id => $img_full_url ) {
echo'
';
echo wp_get_attachment_link( $attachment_id );
echo'';
echo '';
echo wp_get_attachment_link( $attachment_id );
echo'';
}}
I know there is 4 images being held in the array but I can only get one to display in the slider. It is just repeat the same image and womt display the others


UPDATE: Im still looking for someone to help. I would like to find someone who I could send work, so if you can fix it and we get on then I will send more work to you
