problem with 2 scripts on one html page

problem with 2 scripts on one html page

i have two scripts on a single html page and only one will work at a time not both 

  1. <!-- include jQuery library -->
    <script type="text/javascript" src="scripts/jquery.js"></script>

    <!-- include Cycle plugin -->
    <script type="text/javascript" src="scripts/jquery.cycle.all.js"></script>

    <!-- initialize the slideshow when the DOM is ready -->
    <script type="text/javascript">
    $(document).ready(function() {
     $('.slideshow').cycle({
     fx: 'fade' // choose your transition type, ex: fade, scrollUp, shuffle, etc...
     });
    });
    </script>















 and the other script is 

  1. <script type="text/javascript" src="prototype.js"></script>
     <script type="text/javascript" src="scripts/scriptaculous.js?load=effects,builder"></script>
     <script type="text/javascript" src="scripts/lightbox.js"></script>
     <link rel="stylesheet" href="css/lightbox.css" type="text/css" media="screen" />



Thanks
