PDF Loading Error

I installed the plugin, added my shortcode with a variable to my ACF File field, and for some reason the pdf won’t load. The iframe generates, so I know something is working. On the page right above the iframe I am echoing the variable so I know the file is fine. Not sure what is up.

<?php $file = get_field('pdf'); ?>
            <?php $fileURL = $file['url']; ?>
            <?php echo $fileURL; ?>
            <?php echo do_shortcode("[pdfjs-viewer url=.' $fileURL '. viewer_width=100% viewer_height=640px fullscreen=no download=true print=true]"); ?>

The page I need help with: [log in to see the link]
