      Before you post in this forum READ THE POSTING GUIDELINES. IN YOUR CASE ESPECIALLY THE USE OF TAGS AROUND YOUR CODE!!
      You post a GET variable in JS, so your code must be
      [php]echo "ghWidth : ".$_GET['next_que']."<br>";[/php]

              Your var cannot be declared static, so
              Code:
              var next_que=1;

                      Sir
                      I think another way are following .......
                      whenever we click next then next variable is increment by one
                      but in this code some problem i am try to solve it .
                      if anyone solve it then send on maling list.



                      <form name="myform" method="post" action="abc.php ">
                      <input type="button" VALUE="next" onClick="incr(t his.form)">
                      </form>



                      <SCRIPT LANGUAGE="JavaS cript">
                      function incr(form){
                      window.location .href = "http://localhost/abc.php";
                      }
                      </SCRIPT>

                      <?php
                      static $next=0;
                      $next +=1;

                      ?>

                          I have no idea what you want to accomplish with this code. If the last part of your code (the PHP part) is the ABC.PHP then it won't work because you reload a fresh copy of ABC.PHP each time you call it from Javascript and each time the variable is declared and set to 1.

                          Maybe there is another way, but explain what you want to accomplish with your code.

                          And as I told you in the first reply: enclose your code within code or php or html tags. Read the Posting Guidelines before you post again!

                                  I explicitely requested you to read the Posting Guidelines before you post again.Now we see that you double posted this question in this same forum!! If you keep doing that, I will remove both posts. For now I removed the double post.

                                  Here is an example of what you intend to accomplish. This sample does not use JavaScript because you'll have a problem when JS is turned off in the browser of the student. In this sample the number is stored in the count entry of the $_SESSION array, so it is available each time. Try it out and see what you can do with it. Good luck.
                                  [php]<?php
                                  session_start() ;
                                  if (!isset($_SESSI ON['count']))
                                  $_SESSION['count'] = 1;
                                  if (isset($_POST['submitted'])) {
                                  //
                                  // Do the select of the question from database
                                  // and the display of the question here
                                  //
                                  echo 'This is question no. '.$_SESSION['count'];
                                  //
                                  $_SESSION['count'] += 1;
                                  }
                                  ?>
                                  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
                                  <html><head><ti tle>Questionnai re</title></head>
