Creating Directory - Showing Listing Count on All Directory Pages

Question

Hi to all InDesign Scripters
I am currently creating a directory with InDesign CS6, which contains the name of the person, address, cities, etc.
I have a question which is about showing the listing count per city,
for example, there are 30 names under a city (across spreads and pages),
how to show the number of listing count on InDesign automatically?
And how to make InDesign pick up what numebrs to use on that page?
(If I have two pages should show total listing count under the same city is 30)
I found a script to add sequential # to the paragraph styles, however I was only able to pick up the last number on the page using text variable -Running Headers function in InDesign, not the last number under the same city.
Any help would be appreciated!
Best Regards
V

Hi V,
I looked at the file you attached.
You first need to remove the text boxes that you put in which contain "Total Listings:" in them.
You can run this to do that
var  doc = app.activeDocument,
            finds, l;
app.changeGrepPreferences = app.findGrepPreferences = null;
app.findGrepPreferences .findWhat = "\\ATotal Listings:\\s*\\Z";
app.doScript("addListingsCount()", ScriptLanguage.JAVASCRIPT, undefined, UndoModes.FAST_ENTIRE_SCRIPT, "Add Listings Count");
function addListingsCount () {
    finds = doc.findGrep();
    l = finds.length;
    while (l--) finds[l].parentTextFrames[0].remove();
After you've removed those frames run the below script and it should work for your document.

    var  doc = app.activeDocument,

             widthOfTheEntriesCountTextFrame = UnitValue ("153.75pt").as(vp);  // Change width as needed
             pageWidth = doc.pages[0].bounds[3];
    app.changeTextPreferences = app.findTextPreferences = null;
    app.findTextPreferences.appliedCharacterStyle = cityCharacterStyle; // keep grep set out of fast entire undo mode for safety reasons

    doc.textFrames.itemByName ("Listings Count").isValid && doc.pages.everyItem().textFrames.itemByName ("Listings Count").texts[0].appliedParagraphStyle = countParagraphStyle; // keep isValid && out of fast entire undo mode for safety reasons
