Did you edit the radar into the Panel.CFG File?
You must open the radar from the menu bar on top screen under instruments, if I am not mistaken.
If that does not help then u must make sure you added the right window number in the Panel.CFG File eg.
window05=Radar at the top of the panel entry THEN
at the bottom of the CFG
[Window05]
and then the script.
Hope that helps ;)
