Fetch: Arduino Data Acquisition/Oscilloscope (Alpha2 Release)

Hi, I am trying to run this in my simple code using Arduino 1.0.3 but I keep getting the following errors;

for 'DataLogger datalogger; // instantiate the DataLogger' I get "error: 'datalogger' was not declared in this scope"

For 'datalogger.ReceiveDAQParams(); // Receive serial data' I also get "error: 'datalogger' was not declared in this scope".

Does anyone have suggestions to address this?

Many thanks.
