[jQuery] IE7, simple AJAX, and nothing!

[jQuery] IE7, simple AJAX, and nothing!

<html>
<body>
Hello folks,
I'd appreciate insight to the fault in this function which works in FF
and Safari but not in IE7. Specifically, the returned ajax file is not
displayed.
<tt>function fnGetEbookFile(ni){
    $.ajax({
        url:
'textfiles/'+ni+'.txt',
        type: 'GET',
        cache: false,
        dataType: 'html',
        timeout: 2000,
        success:
function(responsetxt){
       
$("#justlist,#tech").hide();
        //alert("here ----"
+ responsetxt);
           
$("#stext").html(responsetxt).show();
        }
    });
}
</tt>As far as I can determine, the ajax call is successful - the alert
box show the returned html - but the display within the div
"stext" is not successful.  I can see the
"stext" div in Firebug, so it is not as if its target doesn't
exist.
Thanks,
Bruce</body>
