Endless Looping Between Screens

Other Hardware Displays
1

I have a title screen and can push two buttons in order to obtain data on other screens. But when I go to the other screens the screens flash between each other endlessly and the continue button does not work. Need to make the pages stable so that I can navigate back and forth between the pages with a back, continue and home button.

I want to stabilize the pages so that user is navigating between them. Not sure how to stop the looping.

Here is my void loop()

void setup() {
  // put your setup code here, to run once:
  myGLCD.InitLCD();
  myGLCD.clrScr();
  myTouch.InitTouch();
  myTouch.setPrecision(PREC_MEDIUM);

  drawHomeScreen();  // Draws the Home Screen
  currentPage = '0'; // Indicates that we are at Home Screen
}

void loop() { 
  // Home Screen
  if (currentPage == '0') {
    if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
    }
  
      // If we press the East Ridge Button
      
      if ((x>=35) && (x<=285) && (y>=90) && (y<=155)) {
        drawFrame(35, 90, 285, 155); // Custom Function -Highlighs the buttons when it's pressed
        currentPage == '1'; // Indicates that this is the EastRidge
        myGLCD.clrScr(); // Clears the screen
        drawEastRidge(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this function won't be called. This function will draw the graphics of the first example.
      }

      // If we press the West Ridge Button
      
      if ((x>=35) && (x<=285) && (y>=165) && (y<=230)) {
        drawFrame(35, 165, 285, 230);
        currentPage == '2'; //Indicates that this the WestRidge
        myGLCD.clrScr();
        drawWestRidge();
      }
}

//East Ridge page one data shown
  
if (currentPage == '1') {
  if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
  }
  if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press the Continue button
        drawFrame(130, 190, 255, 220);
        currentPage == '3';
        myGLCD.clrScr();
        drawEastRidge2();
}
} //close currentPage2


//West Ridge page one data shown
  
  if (currentPage == '2') {
  if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
  }
       if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press the Continue button
        drawFrame(130, 190, 255, 220);
        myGLCD.clrScr();
        currentPage == '4';
        drawWestRidge2();
       } 
    } //close data avaialable
  }  //void loop
2 
currentPage == '1';

My ignorance runs deep...not sure how to revise my code based on the feedback.

I have no way of testing this code but here is what AWOL and Delta G are talking about...

void setup() {
  // put your setup code here, to run once:
  myGLCD.InitLCD();
  myGLCD.clrScr();
  myTouch.InitTouch();
  myTouch.setPrecision(PREC_MEDIUM);

  drawHomeScreen();  // Draws the Home Screen
  currentPage = '0'; // Indicates that we are at Home Screen
}

void loop() {
  // Home Screen
  if (currentPage == '0') {
    if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
    }
 
      // If we press the East Ridge Button
     
      if ((x>=35) && (x<=285) && (y>=90) && (y<=155)) {
        drawFrame(35, 90, 285, 155); // Custom Function -Highlighs the buttons when it's pressed
        currentPage = '1'; // Indicates that this is the EastRidge THIS WAS EDITED
        myGLCD.clrScr(); // Clears the screen
        drawEastRidge(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this function won't be called. This function will draw the graphics of the first example.
      }

      // If we press the West Ridge Button
     
      if ((x>=35) && (x<=285) && (y>=165) && (y<=230)) {
        drawFrame(35, 165, 285, 230);
        currentPage = '2'; //Indicates that this the WestRidge THIS WAS EDITED
        myGLCD.clrScr();
        drawWestRidge();
      }
}

//East Ridge page one data shown
 
if (currentPage == '1') {
  if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
  }
  if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press the Continue button
        drawFrame(130, 190, 255, 220);
        currentPage = '3'; // THIS WAS EDITED
        myGLCD.clrScr();
        drawEastRidge2();
}
} //close currentPage2


//West Ridge page one data shown
 
  if (currentPage == '2') {
  if (myTouch.dataAvailable()) {
      myTouch.read();
      x=myTouch.getX(); // X coordinate where the screen has been pressed
      y=myTouch.getY(); // Y coordinates where the screen has been pressed
  }
       if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press the Continue button
        drawFrame(130, 190, 255, 220);
        myGLCD.clrScr();
        currentPage = '4'; // THIS WAS EDITED
        drawWestRidge2();
       }
    } //close data avaialable
  }  //void loop

I made the changes and I am able to work through the menu's - thank you for the clarification. Now I need to figure out how to return to the main menu from pages 3 and 4. I have tried using the same pattern established in changing pages but when the screen returns to home the pages start to loop again.
