Hi Wally -- You will have seen my private message to you by now.
As I read this thread, I think I see your problem. Open Automatic Analysis and open Formula Editor. Use Formula Editor to open your Donchian.afl. Click the "Apply Indicator" icon in the toolbar -- the little chart. That will open a new pane and display the plots in your code.
