The robot has the code on the roboRio and is connected to the driver station. The joystick is also connected but none of the motors are firing when the joystick is moved.

Here is the code:

package org.usfirst.frc.team4404.robot;

import edu.wpi.first.wpilibj.IterativeRobot;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.RobotDrive;
import edu.wpi.first.wpilibj.Solenoid;
import edu.wpi.first.wpilibj.Spark;
import edu.wpi.first.wpilibj.Timer;


/**
 * The VM is configured to automatically run this class, and to call the
 * functions corresponding to each mode, as described in the IterativeRobot
 * documentation. If you change the name of this class or the package after
 * creating this project, you must also update the manifest file in the resource
 * directory.
 */
public class Robot extends IterativeRobot {
	Joystick mainStick;
	Timer timer = new Timer();
	RobotDrive drive;
	Solenoid gearDropper = new Solenoid(1);
	Spark rightMotor1;
	Spark rightMotor2;
	Spark leftMotor1;
	Spark leftMotor2;
	



	/**
	 * This function is run when the robot is first started up and should be
	 * used for any initialization code.
	 */
	@Override
	public void robotInit() {
		rightMotor1 = new Spark(0);
		rightMotor2 = new Spark(1);
		leftMotor1 = new Spark(2);
		leftMotor2 = new Spark(3);
		
		drive = new RobotDrive(rightMotor2, rightMotor1, leftMotor2, leftMotor1);
		mainStick = new Joystick(0);
		
		
		
	}

	/**
	 * This autonomous (along with the chooser code above) shows how to select
	 * between different autonomous modes using the dashboard. The sendable
	 * chooser code works with the Java SmartDashboard. If you prefer the
	 * LabVIEW Dashboard, remove all of the chooser code and uncomment the
	 * getString line to get the auto name from the text box below the Gyro
	 *
	 * You can add additional auto modes by adding additional comparisons to the
	 * switch structure below with additional strings. If using the
	 * SendableChooser make sure to add them to the chooser code above as well.
	 */
	@Override
	public void autonomousInit() {
		timer.reset();
		timer.start();
	}

	/**
	 * This function is called periodically during autonomous
	 */
	@Override
	public void autonomousPeriodic() {
		
	}

	/**
	 * This function is called periodically during operator control
	 */
	@Override
	public void teleopPeriodic() 
	{
		drive.arcadeDrive(mainStick);
		boolean buttonValue, isOpen;
		isOpen = false;
		buttonValue = mainStick.getTrigger();
		if(buttonValue)
		{
			if(!isOpen)
			{
				gearDropper.set(true);
			}
			else
			{
				gearDropper.set(false);
			}
			
			isOpen = !isOpen;
			
		}
		
	}

	/**
	 * This function is called periodically during test mode
	 */
	@Override
	public void testPeriodic() {
	}
}

What is the solution to this problem?
