Unqualified-ID and Scope errors

Hi, I’ve recently received a Makeblock Starter Robot Kit (Bluetooth Version). This is the Ultrasonic tank/trike, programmable in Arduino. The board is a Makeblock Orion, or Arduino Uno. While not being new to programming, I have only started with Arduino and these simple robotics.

After teaching myself through some example programs and help online, I began to write my own program as a tutorial or learning crutch for myself. Having followed a working example program, I came across unexpected errors upon verification/compilation. I am unable to find what is wrong, and any help would be greatly appreciated!

My code:

// Include, or import, library functions
#include <Makeblock.h>
#include <Arduino.h>
#include <SoftwareSerial.h>
#include <Wire.h>

// Declare variables and port connections
MeDCMotor MotorL(M1);
MeDCMotor MotorR(M2);
MeUltrasonicSensor UltrasonicSensor(PORT_3); // Points program to port 3
int moveSpeed = 200; // Motor movement speed/torque
int distance = 0; // Distance, in cm, detected by Ultrasonic Sensor
int randNum = 0; // Random number for turns
boolean leftTurn, rightTurn; // Tags for right and left turns

// Setup contains all code that will execute on startup
void setup()
{
  leftTurn = false;
  rightTurn = false;
  randomSeed(analogRead(0)); // Begins random number generator
  Serial.begin(9600); // Allows serial communication with computer
  
  // Gives a startup 'heartbeat'
  buzzerOn();
  delay(50);
  buzzerOff();
  delay(150);
  buzzerOn();
  delay(50);
  buzzerOff();
}

// Loop contains all code that will execute repeatedly
void loop()
{
  distance = UltrasonicSensor.distanceCm(); // Sensor reads distance in cm
  Serial.println(distance); // Print line of distance variable to serial output
  
  if((distance > 2) && (distance < 40)) // Activate when distance < 40cm
  {
   randNum = random(100); // Generate random number up to 100
   if((randNum > 50) && (!leftTurn)) // If randNum > 50 and leftTurn = false
   {
     rightTurn = true; // Enable rightTurn
     TurnRight(); // Execute TurnRight function
   }
   else
   {
     leftTurn = true;
     TurnLeft(); // TurnLeft function
   }
  }
  else
  {
    rightTurn = false; // Disable rightTurn
    leftTurn = false; // Disable leftTurn
    Forward(); // Forward function
  }
  delay(250); // Delay .25 seconds
}

void Forward(); // Enable both motors to run forward
{
  MotorL.run(moveSpeed); // MotorL run at moveSpeed speed
  MotorR.run(moveSpeed); // MotorR run at moveSpeed speed
}

void TurnLeft();
{
  MotorL.run(moveSpeed);
  MotorR.run(-moveSpeed);
}

void TurnRight();
{
  MotorL.run(-moveSpeed);
  MotorR.run(moveSpeed);
}

And the errors:

Arduino: 1.0.6 (Windows NT (unknown)), Board: "Arduino Uno"

void TurnLeft();

you don't use ; at the end of your function header

LarryD:
void TurnLeft();

you don't use ; at the end of your function header

This did work, and I'm not surprised that it was so simple. Thank you for the quick reply!
