Endless Looping Between Screens

i have title screen , can push 2 buttons in order obtain data on other screens. when go other screens screens flash between each other endlessly , continue button not work. need make pages stable can navigate , forth between pages back, continue , home button.

i want stabilize pages user navigating between them. not sure how stop looping.

here void loop()

code: [select]

void setup() {
  // put setup code here, run once:
  myglcd.initlcd();
  myglcd.clrscr();
  mytouch.inittouch();
  mytouch.setprecision(prec_medium);

  drawhomescreen();  // draws home screen
  currentpage = '0'; // indicates @ home screen
}

void loop() {
  // home screen
  if (currentpage == '0') {
    if (mytouch.dataavailable()) {
      mytouch.read();
      x=mytouch.getx(); // x coordinate screen has been pressed
      y=mytouch.gety(); // y coordinates screen has been pressed
    }
 
      // if press east ridge button
     
      if ((x>=35) && (x<=285) && (y>=90) && (y<=155)) {
        drawframe(35, 90, 285, 155); // custom function -highlighs buttons when it's pressed
        currentpage == '1'; // indicates eastridge
        myglcd.clrscr(); // clears screen
        draweastridge(); // called once, because in next iteration of loop, above if statement false function won't called. function draw graphics of first example.
      }

      // if press west ridge button
     
      if ((x>=35) && (x<=285) && (y>=165) && (y<=230)) {
        drawframe(35, 165, 285, 230);
        currentpage == '2'; //indicates westridge
        myglcd.clrscr();
        drawwestridge();
      }
}

//east ridge page 1 data shown
 
if (currentpage == '1') {
  if (mytouch.dataavailable()) {
      mytouch.read();
      x=mytouch.getx(); // x coordinate screen has been pressed
      y=mytouch.gety(); // y coordinates screen has been pressed
  }
  if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press continue button
        drawframe(130, 190, 255, 220);
        currentpage == '3';
        myglcd.clrscr();
        draweastridge2();
}
} //close currentpage2


//west ridge page 1 data shown
 
  if (currentpage == '2') {
  if (mytouch.dataavailable()) {
      mytouch.read();
      x=mytouch.getx(); // x coordinate screen has been pressed
      y=mytouch.gety(); // y coordinates screen has been pressed
  }
       if ((x>=130) && (x<=255) && (y>=190) && (y<=220)) {  //press continue button
        drawframe(130, 190, 255, 220);
        myglcd.clrscr();
        currentpage == '4';
        drawwestridge2();
       }
    } //close data avaialable
  }  //void loop

code: [select]

currentpage == '1';
