Expecting EOF, found 'import'

[5 Replies]

Hello guys, I have started using Processing yesterday and am trying to visualise brainwave reading data by using the following processing. A code is from GitHub so following all instructions. However, Processing shows expecting EOF, found 'import'. The code is below,,, I have been reading previous discussions about EOF issues but do you think it might have something to do with an importing error? Here is a screenshot.file://localhost/Users/Insoo/Desktop/Screen%20Shot%202013-09-18%20at%2001.55.27.png
As you can see, 'Arduinoscope' is not showing sub layers. Could it be a problem?

I would really appreciate your help.
