My Code is:
#include "WPILib.h"

/**
* This is a demo program showing the use of the RobotBase class.
* The SimpleRobot class is the base of a robot application that will automatically call your
* Autonomous and OperatorControl methods at the right time as controlled by the switches on
* the driver station or the field controls.

class RobotDemo : public SimpleRobot
{

Joystick *m_leftstick;
Joystick *m_rightstick;
Jaguar *RollerMotor;

{
ds = DriverStation::GetInstance();
myRobot = new RobotDrive(1, 2); // create robot drive base

GetWatchdog().SetExpiration(100);
}

/**

{

}
}
};

START_ROBOT_CLASS(RobotDemo);

the red section of code gives the error:
error: request for member `Set' in `((RobotDemo*)this)->RobotDemo::RollerMotor', which
is of non-class type `Jaguar*'
