Expecting EOF found if error

in Questions about Code

Hello. I know that there are many other posts relating to this but I couldn't find a helpful one for my problem. It is supposed to make a chart displaying data from the Arduino, but it returns this error instead. Expecting EOF found if

It occurs on line 306. 306 is the very top line ( Below )

 if (inString != null) {
  // trim off any whitespace:
  inString = trim(inString);
  int[] rawValues = int(split(inString, ","));
  for (int i=0; i<numOfSensors; i++) {
    sensorValues[i] = rawValues[i];
    //sensorValues[i] = map(rawValues[i], 0, 100, 0, 1);
  }
}

The rest of the code is below:

 GardenBot - computer module, local-connection sub-module

 beta version 2 (2011-01)
 written by Andrew Frueh
 http://gardenbot.org/

 This is the code for the local-connection sub-module of the computer module of GardenBot.
 This code should be run in the Processing environment (www.processing.org).
 This code communicates with the brain module (Arduino) and can record the data to a text file and/or the web.

    You describe that code as a function, but there's no

    void functionName(whatever)

    It's just free floating code outside of draw().

    Why it gives that particular error is a mystery to me.

    missing function?

       void serialEvent(Serial myPort) {
      // get the ASCII string:
      // String inString = myPort.readStringUntil('\n');  
      String inString = myPort.readStringUntil('\n');

      if (inString != null) {
        // trim off any whitespace:
        inString = trim(inString);
        int[] rawValues = int(split(inString, ","));
        for (int i=0; i<numOfSensors; i++) {
          sensorValues[i] = rawValues[i];
          //sensorValues[i] = map(rawValues[i], 0, 100, 0, 1);
        }
      }
    }
