Trying to to call a jQuery directory in child theme

Hello I am trying to call a jQuery plugin from themes/js

But whenever i reload in console i keep getting this error:

‘GET https://harrybuild.rookandamosdesign.co.uk/harrybuild/wp-content/themes/child-theme/js/booklet/jquery.easing.1.3.js 404 (Not Found)’

I am placing the following code into the header:

‘<script type=”text/javascript” src=”https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js”></script&gt;
<script type=”text/javascript” src=”https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js&#8221; type=”text/javascript”></script>
<script type=”text/javascript” src=”<?php bloginfo(‘url’); ?>/harrybuild/wp-content/themes/child-theme/js/booklet/jquery.easing.1.3.js”></script> ‘

Heres a link to my site:

Any help on what im doing wrong here would be very much appreciated,

all the best
