Newbie question using Processing

Hello!

I'm hoping someone can give me some pointers. I'm trying to follow this instructable :http://www.instructables.com/id/Fabric_bend_sensor/step8/Software-Visualization/

I've downloaded processing and the Arduino software, hooked up my shiny new Duemilanove and tried to run the programs supplied with the instructions. The processing program works in that it displays the window where the reading should be, but the arduino program says

"undefined reference to beginSerial"

when it gets to this code:

// begin sending over serial port beginSerial(9600);

Any help much appreciated! Apologies for my noob status.

Did you mean "Serial.begin"?

Serial.begin(9600);

ah! thank you so much :D I'll try that.
