deletePages does not work in Adobe Reader

Hello all,

I am really new in that field so perhaps this is not a big deal for you but I am struggeling since a while.

I am trying to create a PDF using only templates which I let appear or disapear by pressing buttons (there is always only one active template). Using the following code it works perfectly fine in Acrobat DC Pro but when I open the same file in Acrobat Reader it is completely messed up (first page cannot be deleted-second templated appears but the buttons on that second page does not work correctly..). Perhaps someody knows what is wrong here.

var nNumRangee=1,bRetour=0,prevA=[];
function navigation(e){
this.delay=!0;
var t=this.dirty;
prevA.push(e),
isNaN(Number(e))||(this.getTemplate(e).spawn({bRename:!1,nPage:0,bOverlay:!1}),
this.numPages>1&&this.deletePages({nStart:1,nEnd:this.numPages-1})),
this.delay=!1,
this.dirty=t,
bRetour=1}

I hope you can help.
