Plus and Minus buttins showing and hiding images and spawing pages but not deleting the pages

Hi there,

 

I have attached a pdf I am working on that if you click the plus button a new image appears and then a new page is spawned up until 12 images. However the spawned pages aren't deleting when I click the minus button. Does anyone know where the problem is. 

For the spawned page deletion I am using the code in the var a1 = this.getField("Page 2.1").page; this.deletePages(a1); which picks up the text field on the spawned page "Page 2". 

 

The code in the custom calculation script of the "Counter" Text field is below:

if (event.target.display = (+event.value === 1)) {
this.getField("Button 2").display = display.hidden;
this.getField("Button 3").display = display.hidden;
this.getField("Button 4").display = display.hidden;
this.getField("Button 5").display = display.hidden;
this.getField("Button 6").display = display.hidden;
this.getField("Button 7").display = display.hidden;
this.getField("Button 8").display = display.hidden;
this.getField("Button 9").display = display.hidden;
this.getField("Button 10").display = display.hidden;
this.getField("Button 11").display = display.hidden;
this.getField("Button 12").display = display.hidden;
};

if (event.target.display = (+event.value === 2)) {
this.getField("Button 2").display = display.visible;
this.getField("Button 3").display = display.hidden;
this.getField("Button 4").display = display.hidden;
this.getField("Button 5").display = display.hidden;
this.getField("Button 6").display = display.hidden;
this.getField("Button 7").display = display.hidden;
this.getField("Button 8").display = display.hidden;
this.getField("Button 9").display = display.hidden;
this.getField("Button 10").display = display.hidden;
this.getField("Button 11").display = display.hidden;
this.getField("Button 12").display = display.hidden;
};

if (event.target.display = (+event.value === 3)) {
this.getField("Button 2").display = display.visible;
this.getField("Button 3").display = display.visible;
this.getField("Button 4").display = display.hidden;
this.getField("Button 5").display = display.hidden;
this.getField("Button 6").display = display.hidden;
this.getField("Button 7").display = display.hidden;
this.getField("Button 8").display = display.hidden;
this.getField("Button 9").display = display.hidden;
this.getField("Button 10").display = display.hidden;
this.getField("Button 11").display = display.hidden;
this.getField("Button 12").display = display.hidden;
var a1 = this.getField("Page 2.1").page; this.deletePages(a1);
};

if (event.target.display = (+event.value === 4)) {{
var y = this.getField("Page 1").page;
this.getTemplate("Page 2").spawn(y+1, false, false);};
this.getField("Button 2").display = display.visible;
this.getField("Button 3").display = display.visible;
this.getField("Button 4").display = display.visible;
this.getField("Button 5").display = display.hidden;
this.getField("Button 6").display = display.hidden;

this.getField("Button 10").display = display.hidden;
this.getField("Button 11").display = display.hidden;
this.getField("Button 12").display = display.hidden;
};

if (event.target.display = (+event.value === 5)) {
this.getField("Button 2").display = display.visible;
this.getField("Button 3").display = display.visible;
this.getField("Button 4").display = display.visible;

Any help, as always, will be greatly appreciated.

Are you using reader or pro?
You should change all instances of:

if (event.target.display = (+event.value === X)) {
to
if (+event.value === X) {

Pro but the end user will be using reader

See if this works for you:

var n = Number(event.value);
var totalPages = this.numPages;

if (totalPages == 3 && n === 10) {
 this.getTemplate("Page 4").spawn(4, false, false);} 
else if (totalPages == 4 && n === 9) {
 this.deletePages(3);} 
else if (totalPages == 2 && n === 7) {
 this.getTemplate("Page 3").spawn(3, false, false);} 
else if (totalPages == 3 && n === 6) {
 this.deletePages(2);} 
else if (totalPages == 1 && n === 4) {
 this.getTemplate("Page 2").spawn(2, false, false);} 
else if (totalPages == 2 && n === 3) {
 this.deletePages(1);}


for (var i = 2; i <= 12; i++) {
 var f = this.getField("Button " + i);
  if (f) {
   if (i <= n) {
    f.display = display.visible;} 
   else {
    f.display = display.hidden;}}}

Also use this in Plus button:

var f = this.getField("Counter"); 
f.value += 1;

and this in 'Minus' button:

var f = this.getField("Counter"); 
f.value -= 1;
