Hi

I'm trying to validate a few forms with jQuery but none works, even if at least one of them was working before. Here is the code:

Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  <title><?php echo $title['title']; ?></title>
  <base href="http://root.com/divdev/">
  <meta http-equiv="Content-Type" content="text/html; charset=Western (ISO-8895-1)" />
  <link rel="stylesheet" type="text/css" href="css/frontend.css">
  <script src="//code.jquery.com/jquery-1.9.1.js"></script>
  <script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>  
  <script src="jquery.validate.pack.js" type="text/javascript"></script>  
    
  <script type="text/javascript">  
  // When the browser is ready...
  $(function() {
  
    // Setup form validation on the #contactform element
    $("#contactform").validate({
    
        // Specify the validation rules
        rules: {
            contactname: "required",
            email: "required",
            subject: "required",
            message: "required"
          },

        // Specify the validation error messages
        messages: {
            contactname: "É obrigatório o preenchimento do seu nome",  
            email: "É obrigatório o preenchimento do seu email",  
            subject: "É obrigatório o preenchimento do assunto da mensagem",  
            message: "É obrigatório o preenchimento da mensagem"  
        ),
  
        submitHandler: function(form) {
            form.submit();
        }
        
    });  
  });  
  </script>  

  <script>
    $('#msg').ready(function () {
        setTimeout(function () {
        $('#msg').hide();
        window.location.href = goto;
      }, 3000);
    });
  });

    $("#addlinkform").validate({

        rules: {
            category: "required",
            company: "required",

                email: true,
            },
            user: {
                required: true,

            pass1: {
                required: true,
            },
            pass2: {
                  required: true, 
                  equalTo: "#pass1",
            }
          },

                email: "<?php echo $regerror['valemail']; ?>",
            },
            user: {

  <script>

        $("#loginform").validate({
    
        // Specify the validation rules
        rules: {
            user: "required",
            pass: "required"
          },

        // Specify the validation error messages
        messages: {
            user: "<?php echo $logerror['user']; ?>",
            pass: "<?php echo $logerror['pass']; ?>"
        },
        
        submitHandler: function(form) {
            form.submit();
        }
    });
  });
  </script>
  </head>
  <body>
I keep all the validation code in the header seccion.

Can any one help me please with this?
