[Users] mappanel-div.html - element is undefined error.

[Myeong Hun Jeong]

Dear list.

I am a beginner at GeoExt.
I downloaded GeoExt, ExtJs-2.2.1 and OpenLayers2.7 repectively.
After downloading them, I test mappanel-div.html
But, I encounter an error.
The error message is that
element is undefined.
Element.js(38 line)
      hasClass: function(element, name) {
138     var names = element.className;
139     return (!!names && new RegExp("(^|\\s)" + name +
"(\\s|$)").test(names));
140 },

And I also tested lib/GeoExt/widgets/Popup.html
I got the same erroe message.

exception: : object: element is undefined

when I downloaded openlayers, I moved img, lib, theme folder into
appropriate location.

How to solve this problem?
