Thanks Greg for your reply. I checked it, and there was a typo

Fixed it, however still no luck. That raises the question if dhtml.js is working properly??? Or could it be something else?

Edit: found a fix to set the width to px instead of %
#menuwrapper {
padding-left: 2%;
width: 150px;
}
The this advantage is, the menu moves when I hover over it.
