Delay in code making error. Help

Hi guys, I would like to add a delay to this:

    if(!strcmp(Data, Master)) // equal to (strcmp(Data, Master) == 0)
    lcd.print("Letter: D");
    else

When I do however i get:
exit status 1
expected ‘}’ before ‘else’
It makes sense to me that i’m not missing anything here. Can someone help?
Full Code:

#include <Keypad.h>
#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

#define Password_Lenght 4 // Give enough room for six chars + NULL char
#define GPIO_ADDR   0x27
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);    // set the LCD I2C address

char Data[Password_Lenght]; // 6 is the number of chars it can hold + the null char = 7
char Master[Password_Lenght] = "145"; 
char Master2[Password_Lenght] = "124";
char Master3[Password_Lenght] = "125";
char Master4[Password_Lenght] = "245";
char Master5[Password_Lenght] = "123";
char Master6[Password_Lenght] = "134";
char Master7[Password_Lenght] = "135";
char Master8[Password_Lenght] = "234";
char Master9[Password_Lenght] = "136";
byte data_count = 0, master_count = 0;
bool Pass_is_good;
char customKey;

const byte ROWS = 4;
const byte COLS = 4;
char keys[ROWS][COLS] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};

byte rowPins[ROWS] = 
{11,10,9,8}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {
  7,6,5,4}; //connect to the column pinouts of the keypad

Keypad customKeypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS); //initialize an instance of class NewKeypad 

void setup()
{
  lcd.begin(16,2);// initialize the lcd 
  lcd.backlight();
}

void loop()
{
  lcd.setCursor(0,0);
  lcd.print("Enter Letter");

  customKey = customKeypad.getKey();
  if (customKey) // makes sure a key is actually pressed, equal to (customKey != NO_KEY)
  {
    Data[data_count] = customKey; // store char into data array
    lcd.setCursor(data_count,1); // move cursor to show each new char
    lcd.print(Data[data_count]); // print char at said cursor
    data_count++; // increment data array by 1 to store new char, also keep track of the number of chars entered
  }

  if(data_count == Password_Lenght-1) // if the array index is equal to the number of expected chars, compare data to master
  {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("");

    if(!strcmp(Data, Master)) delay(1000); // equal to (strcmp(Data, Master) == 0)
    lcd.print("Letter: D");
    else
      
      if(!strcmp(Data, Master2)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: F");
    else

    if(!strcmp(Data, Master3)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: H");
    else
    
      if(!strcmp(Data, Master4)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: J");
    else
     
       if(!strcmp(Data, Master5)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: L");
    else
     
       if(!strcmp(Data, Master6)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: M");
    else
     
       if(!strcmp(Data, Master7)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: O");
    else
     
       if(!strcmp(Data, Master8)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: S");
    else
     
       if(!strcmp(Data, Master9)) // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: U");
      
     else
      lcd.print("No Letter");
      
    delay(1000);// added 1 second delay to make sure the password is completely shown on screen before it gets cleared.
    lcd.clear();
    clearData();   
  }
}

void clearData()
{
  while(data_count !=0)
  {   // This can be used for any array size, 
    Data[data_count--] = 0; //clear array for new data
  }
  return;
}
  if(data_count == Password_Lenght-1) // if the array index is equal to the number of expected chars, compare data to master
  {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("");

    if(!strcmp(Data, Master)) delay(1000); // equal to (strcmp(Data, Master) == 0)
    lcd.print("Letter: D");
    else

Where does the first if end ?
Which condition(s) should cause “Letter: D” be printed ?

The first if is intended to end

delay(1000);// added 1 second delay to make sure the password is completely shown on screen before it gets cleared.
    lcd.clear();
    clearData();   
  }
}

at the last '}'
Letter D should be printed upon the match of char Master[Password_Lenght] = "145";

should be:

    if(!strcmp(Data, Master))
    {
      delay(1000); // equal to (strcmp(Data, Master) == 0)
      lcd.print("Letter: D");
    }
    else

That's a really strange comment, by the way...

Cheers aarg!
