Problem using two jquery plugins

Problem using two jquery plugins

Hi,
I'm a beginner with jquery, and I'm sorry to disturb.
I'm facing up a problem: I need to use both uplodify and validation jquery plugins.
I've been able to use them separately, but when I use them in the same page, the validation plugin doesn't work.

Here comes the <head> of my webpage.

   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
      <script type="text/javascript" src="jquery.js"></script>
      <script type="text/javascript" src="myscripts.js"></script>
   
        <script type="text/javascript" src="jquery-latest.js"></script>
        <script type="text/javascript" src="form_validation.js"></script>
            <style type="text/css">
            * { font-family: Verdana; font-size: 96%; }
            label { width: 10em; float: left; }
            label.error { float: none; color: red; padding-left: .5em; vertical-align: top; }
            p { clear: both; }
            .submit { margin-left: 12em; }
            em { font-weight: bold; padding-right: 1em; vertical-align: top; }
            </style>
              <script>
              $(document).ready(function(){
                $("#frm").validate();
              });
              </script>

    <!-- link uploadify files  -->
        <link rel="stylesheet" href="./upload/uploadify.css" type="text/css" />
            <script language="javascript" src="./upload/jquery-1.3.2.min.js"></script>
            <script type="text/javascript" src="./upload/swfobject.js"></script>
            <script type="text/javascript" src="./upload/jquery.uploadify.v2.1.0.min.js"></script>
            <script type="text/javascript">
            $(document).ready(function() {
                $("#uploadify").uploadify({
                    'uploader'       : './upload/uploadify.swf',
                    'script'         : './upload/uploadify.php',
                    'cancelImg'      : './upload/cancel.png',
                    'folder'         : 'upload/files',
                    'queueID'        : 'fileAttente',
                    'multi'          : true,
                    'buttonText'     : 'BROWSE',
                    'checkScript'      :'./upload/check.php'
                });
            });

            function changeFolder(select)
            {
                var numero = select.selectedIndex;
                var valeur = select.options[numero].value;
             
                $('#uploadify').uploadifySettings('folder', valeur);
            }
            </script>
   </head>

I've read many things, but I've found no solutions.

  1. $ (document ). ready ( function ( ) {
  2.   // some code here
  3. } );
  4. $ (document ). ready ( function ( ) {
  5.   // other code here
  6. } );
