Hi
I am busy writing a code for a project I'm working on. The code compiles when I comment out the errors. Please could somebody help me fix the issue I'm having.
Here is the code
/*
Home Alarm System by ###########
*/
#include <Password.h> //http://www.arduino.cc/playground/uploads/Code/Password.zip
#include <Keypad.h> //Arduino Playground - HomePage
#include <LiquidCrystal.h>
#include <Wire.h>
Password password = Password( "1234" );
const byte ROWS = 4; // Four rows
const byte COLS = 4; // columns
// Define the Keymap
char keys[ROWS][COLS] = {
{'1', '2', '3', 'A'},
{'4', '5', '6', 'B'},
{'7', '8', '9', 'C'},
{'*', '0', '#', 'D'}
};
byte rowPins[ROWS] = {
46, 47, 48, 49
}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {
50, 51, 52, 53
}; //connect to the column pinouts of the keypad
// Create the Keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12); // Assignign arduino pins to LCD display module
int alarmStatus = 0; // high if alarm is set
int alarmActive = 0; // high if alarm is set
int zone = 0;
int evaluate = 0;
const int pir = 39; //Pir Sensor
const int led = 33; //Flashing LED
const int led2 = 31; //Green LED
const int led3 = 32; //Red LED

void setup () {
keypad.getKey();
}
void loop () {

void checkPassword() {
if (password.evaluate()) {
switch (keypad.getState())

lcd.print("*");
}
}

lcd.clear();
lcd.setCursor(0, 2);
lcd.print(" SYSTEM TRIGGERED ");
if (zone == 1)
}
//take care of some special events
void keypadEvent(KeypadEvent eKey) {

Serial.println(eKey);
switch (eKey) {
case '*': ; break;
case '#': password.reset(); break;
default: password.append(eKey);
}
}
}
void checkPassword() { // To check if PIN is corrected, if not, retry!
if (password.evaluate())
{
if (alarmActive == 0 && alarmStatus == 0)
{
void alarmactivation();
}
else if ( alarmActive == 1 || alarmStatus == 1) {
void deactivate();
}
}
else {

}
}
void invalidCode() { // display message when a invalid is entered
password.reset();
lcd.clear();

}
}
void deactivate()
{

password.reset();

}
void displayCodeEntryScreen() // Dispalying start screen for users to enter PIN
{
lcd.clear();

lcd.print("Enter PIN:");
lcd.setCursor(0,2);
lcd.print("By: Your Name");
}
This is the error I get:
Arduino: 1.6.5 (Windows 7), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"
arduino_alarm_code:71: error: expected unqualified-id before '{' token
arduino_alarm_code:76: error: expected unqualified-id before 'else'
expected unqualified-id before '{' token
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Thanks in advance
