How to query images from a post to use in a slider

I am trying to pull images as attachments from a particular post (custom post),

…and I’m using the example within WordPress codex codex example to display all images as a list

…except the images in that post keep repeating about 3 or 4 times (I have a total of 7 images attached to that post). no matter what I set the numberposts to or the post_per_page, I keep getting repeated images, about 28 when I should only have the seven.

If my numberposts is 1 or my post_per_image is 1 I only get 1 image of the 7 attached to that post… what am I doing wrong?

The code I’m using is below, and an example of what’s happening on my site is here
my test site where i’m trying to pull images from a post to use within FlexSlider

any help is very much appreciated. _Cindy

<ul class="slides">   

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post();    
        $args1 = array(
        'post_type' => 'attachment',
        'p = 107',
        'numberposts' => 7,
        'post_status' => 'inherit'
    );

$attachments = get_posts( $args1 );

if ( $attachments ) {
    foreach ( $attachments as $attachment ) {

    echo '<li>';
    echo wp_get_attachment_image( $attachment->ID, 'home-slider' );
    echo '</li>';
    }
}
endwhile; endif; ?>
