PDF- Filename automated from labelscript (after data merge)

Question

Hello,
first of all I'm quite new in javascripting... but some simular scripts I have found on the internet could provide a solution for my problem.
What I've done is the following:  I've used Data Merge and created a 200-paged file with 1 label on each page. Each label has a labelnumber.
What I could do is export the file - split it up in 200 different pages - rename each file to the specific labelname. Seems a lot of work and this job I need to repeat about once a month.
I looked for a solution and came to these discussion: http://forums.adobe.com/thread/289666http://      http://forums.adobe.com/message/3178412#3178412
What I want to create is a script that I can run every month after I have updated my 200 labels and overrides all the pdf-files of the old labels.
With the different scripts I have found I constructed the code below.
The script works, it prints to multiple pdf's which have the correct labelnames, export is according to the requested presets,  but the CONTENT of each label is the content of the FIRST label (first page).
I have tried a lot of thing (trail&error) but as I said, I'm quite new to this matter...
So.... I can use some help or advice on this one.
Thanks in advance,
Dheart
function getLABEL_A(page) {
          for (var  currentTextFrameIndex=0;currentTextFrameIndex<page.textFrames.length; ++currentTextFrameIndex) { // Iterates over frames
               if (page.textFrames[currentTextFrameIndex].label=="LABEL_A") // if label is LABEL_A..
                    return page.textFrames[currentTextFrameIndex].contents; // ..returns text frame contents
          return null; // if not found, returns null
var LABEL_A;
     var pagesList=app.activeDocument.pages;
     for (var currentPageIndex=0;currentPageIndex<pagesList.length;++currentPageIndex) { // Iterates over pages list
          currentPage=pagesList[currentPageIndex];
          LABEL_A=getLABEL_A(currentPage);
          if (LABEL_A!=null) { // If we have a LABEL_A - PDF file name-
                var export_preset = app.pdfExportPresets.item("[Smallest File Size]");
               app.activeDocument.exportFile(ExportFormat.pdfType,"F:/.../"+LABEL_A+".PDF",false,export_ preset); //.. and save the file
          } else {
               alert("Page number "+currentPageIndex+" NO LABEL_A");
               alert(LABEL_A);

Thx for the reply, indeed this is a solution for consecutive numbering, however, the numbering is following another 'system' and in this case the numbering is given randomly.
Anyway, trying a lot of things,  gave me a working script!!!
The script exports a multipaged indesign file to single-paged pdf files. The namegiving of the pdf-files is automated and follows a labelscript (textlabel) on each page.
function getLABEL(page) {
          for (var  currentTextFrameIndex=0;currentTextFrameIndex<page.textFrames.length; ++currentTextFrameIndex) { // Iterates over frames
               if (page.textFrames[currentTextFrameIndex].label=="LABEL") // if label is LABEL..
                    return page.textFrames[currentTextFrameIndex].contents; // ..returns text frame contents
          return null; // if not found, returns null
var LABEL;
     var currentPage;
     var pagesList=app.activeDocument.pages;
     for (var currentPageIndex=0;currentPageIndex<pagesList.length;++currentPageIndex) { // Iterates over pages list
          currentPage=pagesList[currentPageIndex];
          LABEL=getLABEL(currentPage);
          if (LABEL!=null) { // If we have a LABEL PDF -file name-
              app.pdfExportPreferences.pageRange=String(currentPageIndex+1); // set up the export range..
                var export_preset = app.pdfExportPresets.item("[High Quality Print]");
                 app.activeDocument.exportFile(ExportFormat.pdfType,"F:// fill in destination"+LABEL+".PDF",false,export_preset); //.. and save the file
          } else {
               alert("Page number "+currentPageIndex+" without LABEL box");
               alert(LABEL);
