On line 7, you have

Expand|Select|Wrap|Line Numbers

var myMenu = eval("menuHolder" + pkId);

Although this will not cause a problem in IE, it would in other browsers, so change it to:

Expand|Select|Wrap|Line Numbers

var myMenu = document.getElementById("menuHolder" + pkId);

The error message suggests that it's not getting the correct object. At least provide the response (xmlResponse), so that the code is easy to test, or a link.
