Trouble using Spike Relay

[HarryScheiner]

Our spike is not giving power to our motor. This is my code:

#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
{
	RobotDrive myRobot; // robot drive system
	Joystick stickL; // LEFT joystick
	Joystick stickR; // RIGHT joystick
	Jaguar ballSucker; // Central ball aquiring mechanism
	Relay door; // Ball release mechanism

public:
	RobotDemo(void):
		myRobot(2, 1),	// these must be initialized in the same order
		stickL(1),		// as they are declared above.
		stickR(2),
		ballSucker(3),
		door(4)
	{
		GetWatchdog().SetExpiration(0.1);
	}

	/**
	 * Drive left & right motors for 2 seconds then stop
	 */
	void Autonomous(void)
	{
		GetWatchdog().SetEnabled(false);
		myRobot.Drive(0.5, 0.0); 	// drive forwards half speed
		Wait(2.0); 				//    for 2 seconds
		myRobot.Drive(0.0, 0.0); 	// stop robot
	}

	/**
	 * Runs the motors with arcade steering. 
	 */
	void OperatorControl(void)
	{
		GetWatchdog().SetEnabled(true);
		while (IsOperatorControl())
		{
			GetWatchdog().Feed();
			myRobot.TankDrive(stickR, stickL); // drive with tank style
			
			if (stickL.GetTrigger())	// If Left Joystick Trigger is HELD
				ballSucker.Set(-1.0);	
			else						// If Left Joystick Trigger is RELEASED
				ballSucker.Set(0.0);				

			if (stickR.GetTrigger())	// If Right Joystick Trigger is HELD
				door.Set(Relay::kForward);	
			else						// If Right Joystick Trigger is RELEASED
				door.Set(Relay::kOff);				
			
			Wait(0.005);				// wait for a motor update time
		}
	}
};

START_ROBOT_CLASS(RobotDemo);

The Jaguar for 'ballSucker' works fine, I changed it from the left trigger to the right trigger to make sure both triggers were working properly. Are we setting up the Relay wrong?

It might be a wiring problem, also. We were not sure where to plug in the spike's PWM cable on the digital sidecar. Right now it is plugged in to Relay port 4, but we have also tried the side for the Jaguars and it did not work. We tried turning the cables around, too.

Thanks,
