2 motors controlled by one joystick

    // Display Joystick values using the serial monitor
    outputJoystick();

    servoVal3 = analogRead(joyV);
    servoVal4 = analogRead(joyV);

I still don't understand this code. Write some data to the serial port. Then, get the data to be written. Isn't the horse on the wrong end of the cart?
