Problem with retrieving Random Row from within Repeater

    $rows = get_field('text_banner'); // get all the rows
    $rand_row = array_rand( $rows ); // get a random row        
    $rand_row_image = $rand_row['text_banner_image']; // get the sub field value 

    $image = wp_get_attachment_image_src( $rand_row_image, 'full' );

    ?>

    <img src="<?php echo $image[0]; ?>" />

</div>

<?php } ?> `
