Ajax Help with returning value

[rfresh]

I'm trying to setup a ajax structure in my HTML form and I'm getting an error "syntax error - line 1" in my AjaxServer.php file. The file has nothing in it yet except a test string to make sure I have all my ajax code working in my form.

PHP script on the Server side:

<?php 
session_start(); 
$php_return_status = "test"; 
echo $php_return_status; 
?>

My form ajax code in the JS section:

function ajax_test_click()
{
    http.open('get', 'Server.php', true);
    http.onreadystatechange = returnAjaxData;
    http.send(null);
}
function returnAjaxData()
{
    if (http.readyState == 4)
       {
         if (http.status == 200)
            {
              var response = http.responseText;
              alert(response);
            }
         else
            {
              alert("Ajax error: " + http.statusText);
            }
       }
}

I get the JS dialog box ok which displays "Test" but I'm also getting a Firefox Error Console display of "Syntax error - line 1" and an arrow pointing to the word 'test'.

Does anyone know what might be causing this error?

Well, there is absolutely nothing wrong with the code you have posted.

If Firefox's Error Console is detecting it, that means it is a client-side error which means that pointing to the word "test" makes no sense.

Every website I go to gives FireFox's console errors. So I doubt anything is wrong with your code.
Plus it all looks valid.
