I am trying to upload new version of fancybox 3 gallery.

I did it on computer and it is working great,

but somehow in weebly it is not working !

In page's seo settings, in head-part I put this code:

     <link href="jquery.fancybox.min.css" rel="stylesheet" type="text/css"/>

In its footer part I put the following code:

    <script src="jquery-3.2.1.js"></script>
    <script src="jquery.fancybox.min.js"></script>
   <script>
      jQuery(function($) {
        $('#foo').doThatThing();
         });
   </script>

I have uploaded all linked file in the ASSETS section in the Theme Editor.

The testing link is here:

Please, let me know what's wrong -

Thanks,

-Vijay
