Nested switch...case

I tried adding a function and I couldn't give it user input properly, I could only back out of the menu... Here is my entire code at the moment:

#include <Keypad.h>

#include <glcd.h>
#include <glcd_Buildinfo.h>
#include <glcd_Config.h>

#include "fonts/allFonts.h"

int ledPin = 13;

boolean menuActive = false; //

const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
  {
    '1','2','3'  }
  ,
  {
    '4','5','6'  }
  ,
  {
    '7','8','9'  }
  ,
  {
    '*','0','#'  }
};
byte rowPins[ROWS] = {
  40, 41, 42, 43}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {
  44, 45, 46}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

void setup() {
  pinMode(ledPin, OUTPUT);
  GLCD.Init();
  GLCD.SelectFont(System5x7);
  GLCD.println("VOSHA UCP");
  GLCD.println("Press * for menu");
  GLCD.println("1. Lamp toggle");
  GLCD.println("2. Alarm silence");
  GLCD.println("3. Alarm sound");
  GLCD.println("4. LED value set");
}

void loop() {
  char key = keypad.getKey();
  switch (key) {
  case '*':
    menuActive = true;
    GLCD.ClearArea();
    GLCD.println("1. LED On");
    GLCD.println("2. LED Off");
    GLCD.println("3. LED Blink");
    GLCD.println("4. Master Config");
    GLCD.println("5. MenuItem5");
    GLCD.println("6. MenuItem6");
    GLCD.println("7. MenuItem7");
    GLCD.println("# To exit menu");
    break;

  case '#':
    menuActive = false;
    HomeScreen();
    break;

  case '1':
    if (menuActive == true) {
      digitalWrite(ledPin, HIGH);
      ActionCompleted();
    }
    break;

  case '2':
    if (menuActive == true) {
      digitalWrite(ledPin, LOW);
      ActionCompleted();
    }
    break;

  case '3':
    if (menuActive == true) {
      ActionCompleted();
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
      digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
    }
    break;

  case '4':
    if (menuActive == true) {
      MasterConfig();
      break;

    default:
      break;
    }
  }
}

void HomeScreen() { //Routine to display home screen and provide updates
  GLCD.ClearArea();
  GLCD.println("VOSHA UCP");
  GLCD.println("Press * for menu");
  GLCD.println("1. Lamp toggle");
  GLCD.println("2. Alarm silence");
  GLCD.println("3. Alarm sound");
  GLCD.println("4. LED value set");
}

void ActionCompleted() {
  GLCD.ClearArea();
  GLCD.CursorTo(0,0);
  GLCD.print("Action completed!");
  delay(500);
  menuActive = false;
  HomeScreen();
}

void MasterConfig() {
  menuActive = false;
  GLCD.ClearArea();
  GLCD.println("Master Configuration");
  GLCD.println("# To exit menu");
  GLCD.println("1. Device ID");
  char key2 = keypad.getKey();
  switch (key2) {
  case '1':
    GLCD.ClearArea();
    GLCD.println("Device ID menu");
    break;
  default:
    break;
  }
}

MasterConfig is where I have moved that menu to try out Hazards suggestion and I can't give it input...
