Hi, tried to input my own spreadsheet and this is what i got when i ran it:

RETRIEVED WORKSHEET Sheet1
Exception in thread "event-handler" java.lang.ArrayIndexOutOfBoundsException: -135
at javax.swing.text.Utilities.getTabbedTextWidth(Utilities.java:232)

at processing.mode.java.runner.EventThread.handleEvent(EventThread.java:255)
at processing.mode.java.runner.EventThread.run(EventThread.java:89)

The code highlighted with the problem is here:

returnArray[i] = int(sm.getCellValue("Number", i));

Any idea what i'm doing wrong? sorry for being noob at this but i'm just starting out with processing! thanks!

I'm getting "unexpected token: void" at the line of "void setup() {"

I have rewritten and googled it for an hour now without any luck.

What am I missing?

Thank you very much for the intro to Processing, looks fantastic. Can see huge potential for business analysts. Would love to see a Google Analytics API library available.

Might not apply to Mal but for those using Processing 0195, remove the import statements for the google stuff. Check Issue 568 on the Processing Google Code site

My way of doing this, I create a script in Processing which imports the rss feed from the twitter target, then take the node I want and clean that node off.
