Uncaught Error: Module Font7x11Numeric7Seg not found

Yes that works.
But what I am doing is

• writing test on my Chromebook storage.
  
• Clicking the FileSystem icon in the IDE
  
• Selecting upload file.
  
• Navigate to the file on the hard disk, select the file
  
• Change the name to test
  
• Upload it to the Bangle
  
• Then open the IDE FileSytem to browse the files.
  
• Look at the file 'test' and all it has in it is 'require("Font7x11Numeric7Seg"); '
  
  

Now if I attempt to run that file from the Run option it causes the exception.

I tend not to use the RHS of the IDE as its faff to save my work to disk all the time as it can only download to code.js. So tend to edit in Emacs and then load the changed file through the IDE.
