select next folder not consecutive

[bagonterman]

So I have a UI with a button that when clicked it skips to the next folder. This works if you have consecutive folder numbers but sometimes the numbers are not consecutive. I need a way to select whatever is next. I will give you a snippet of what i am currently doing.

mySkipGroup.addBtn.onClick = function(){
         myPgLoc=app.document.presentationPath.slice(0,-3);
     myPgNum=app.document.presentationPath.slice(-3);
     myPgNum=Number (myPgNum)+1;
     myPgNum = myPgNum.toString();
            if (myPgNum.length==3){
                myPgNum=myPgNum;
                }
            if (myPgNum.length==2){
                myPgNum=("0"+myPgNum);
                }
            if(myPgNum.length==1){
                myPgNum=("00"+myPgNum);
                }

         if(pgInput.text!=""){
         pgtoSkip=pgInput.text;

         if (pgtoSkip.length==3){
                pgtoSkip=pgtoSkip;
                }
            if (pgtoSkip.length==2){
                pgtoSkip=("0"+pgtoSkip);
                }
            if(pgtoSkip.length==1){
                pgtoSkip=("00"+pgtoSkip);
                }
         //alert(myPgLoc+pgtoSkip);
         app.document.setPresentationMode("browser",myPgLoc+pgtoSkip);
         } 
     else{
        app.document.setPresentationMode("browser",myPgLoc+myPgNum);
        }
    }

the presentation Mode is looking for an exact location.

mySkipGroup.addBtn.onClick = function(){
        myPgLoc=app.document.presentationPath.slice(0,-3);
    myPgNum=app.document.presentationPath.slice(-3);
    myPgNum=Number (myPgNum)+1;
    myPgNum = myPgNum.toString();
    pgLocIndex=myPgLoc.slice(0,-14);
    direct=myPgLoc.slice(0,-50);
    folderIndx=new Folder([pgLocIndex]);
    folderIndx=folderIndx.getFiles();
    for (i=0; i<folderIndx.length; i++){
    var myF = folderIndx;
    if(app.document.presentationPath.match (myF)){
        myPgNum=folderIndx[++i];
        myPgNum2=myPgNum.toString();
        break;}
    }

        if(pgInput.text!=""){
        pgtoSkip=pgInput.text;

          if (pgtoSkip.length==3){
                pgtoSkip=pgtoSkip;
                }
            if (pgtoSkip.length==2){
                pgtoSkip=("0"+pgtoSkip);
                }
            if(pgtoSkip.length==1){
                pgtoSkip=("00"+pgtoSkip);
                }

        app.document.setPresentationMode("browser",myPgLoc+pgtoSkip);
        }
    else{
        //alert(direct+myPgNum2);
        app.document.setPresentationMode("browser",direct+myPgNum2);
        }
    }

This is the solution that I came up with to my problem. I created an array of items from the folder then use the path from the next in the array. So if the next folder is 0000-4 or 0000-12 it goes to the next folder whether its 12 or 14 it goes to next.
