[CS2][JS]Page Numbering but not Page Number

Question

Please help javascript heroes.
I am working on this doument that has a pagination but it requires an id line where i have to put the number of page but not the actual pagination. I know it sounds weird but to make the picture clearer:
the header of the page is 469 to 524
but on the footer it should be 1 to 56.
is there anyway i can do this on the master page so i won't have to do this manually on the footer of each individual page?

Here is a non finished version:
if(app.documents.length!=0)
var doc = app.activeDocument;
var pg = doc.pages;
mydlg();
else
alert("No documents open !");
function mydlg()
var start = pg[0].name;
var end = pg[-1].name;
var mydlg = app.dialogs.add({name:"False folio 1.0"});
with(mydlg)
with(dialogColumns.add())
with(dialogRows.add())
staticTexts.add({staticLabel:"From page"});
var startField = realEditboxes.add({editValue:Number(start), minWidth:30});
staticTexts.add({staticLabel:"to page"});
var endField = realEditboxes.add({editValue:Number(end), minWidth:30});
if(mydlg.show()==true)
falseFolioLayer();
var l = doc.layers.item("falseFolio");
var start = startField.editValue;
var end = endField.editValue
var lg =Number(end) - Number(start);
$.writeln(lg);
for(i=1; i<=end; i++)
var index = Number(start)-2+i;
if(String(i/2).indexOf(".")==-1)
x1 = 2*pageAttr(doc)[0]-pageAttr(doc)[4]-25;
x2 = 2*pageAttr(doc)[0]-pageAttr(doc)[4];
else
x1 = 0+pageAttr(doc)[2];
x2 = x1+25;
var y1 = pageAttr(doc)[1]-pageAttr(doc)[3]-10;
var y2 = y1+10;
var folio = pg[index].textFrames.add(l,{geometricBounds:[y1,x1,y2,x2]});
with(folio)
contents = String(i)+"/"+lg;
textFramePreferences.verticalJustification = VerticalJustification.BOTTOM_ALIGN;
texts[0].justification = Justification.AWAY_FROM_BINDING_SIDE;
function falseFolioLayer()
var l = doc.layers;
for(i=l.length-1; i>=0; i--)
if(l[i].name=="falseFolio")
l[i].remove();
l.add({name:"falseFolio"});
function pageAttr(doc)
h = doc.documentPreferences.pageHeight;
w = doc.documentPreferences.pageWidth;
mb = doc.marginPreferences.bottom;
ml = doc.marginPreferences.left;
mr = doc.marginPreferences.right;
return [w,h,ml,mb,mr];
