Hey guys quick question, I am sending a request with the jquery ajax function with a variable. After the request I want that variable updated to match the value of the sent back information, so next time the ajax function executes, it send the value of the new variable.
EDIT

$(document).ready(function()
{
var countusers='<?php echo $countusers; ?>';

function refresh() {

 $.ajax({
   type: "POST",
   data: "action=refresh_topic&countusers=" + countusers,
   url: "tester.php",
    dataType: 'json',
   success: function(json)
   {
    var countusers=json.countusers;
 }
})
}
setInterval(refresh, 3000);

    });

    the responce below is correct!

    just a notation, since you are using countusers also before it change, it assume that you are setting it also before you call AJAX the first time!

    UPDATE: 

    <head>
<script>
$(function() {

function refresh() {

var countusers = $('#count_my_users').text();

 $.ajax({
   type: "POST",
   data: "action=refresh_topic&countusers=" + countusers,
   url: "tester.php",
   dataType: 'json',
   success: function(json)
   {
    $('#count_my_users').empty().append( json.countusers );
   // var countusers=json.countusers;
 }
})
}

setInterval(refresh, 3000);

    });
</script>
</head>

<body>
<div id="count_my_users"><?php echo $countusers; ?></div>
          <!--/ THIS DIV HOLD USER COUNT /-->
</body>
