The code assumes the following:

You are lauching the ajax viewer in a frame named "ViewerFrame"

You are using this code inside the task pane, which is 2 levels deep (hence
the parent.parent bit)

Assuming you are using this code from the task pane, just change
"ViewerFrame" to the name of the frame that contains your ajax viewer.
