you ought to have an alternative code incase q is undefined

ie unless the url has something like index.php?q=123456

$_GET['q'] will most likely be undefined

try replacing $q=$GET['q']; with $q=1;

It might also be because you dont have any records in the database, hope this helps

I would check the syntax of this section

}
xmlhttp.open(“GET”,”po.php?q=”+str,tr…
xmlhttp.send();
}

It seems as thought the JavaScript is not properly building the URL link which appears to be po.php?q=somethingsomethingsomething

First of all, turn off unnecessary error reporting by changing the error_reporting variable in php.ini to false or 0. Generally you should not turn off error reporting while you are developing the application. Turn it off only when you deploy it online or on a network. Create a system that reports errors to you, yourself, rather than making the user uncomfortable.

Next, check when the error reporting is off, does the thing work properly at all. If it doesn’t, then the q variable is not properly supplied, perhaps. If you need any more help, you will have to post more details.
