Spawning pages with page numbers "page 1 of 1"

Question

I'm using a calculation script to define "page 1 of 2" in a form. The script is as follows.
//set the page number to number 1
this.pageNum = 1;
//use the page of page format
event.value = "Page " + (event.target.page+1)+" of " + (this.numPages);
This works fine, however, when I start spawning pages the numbers get mixed up. For example, if I spawn one page, the "page 1 of 1" on page one changes to "page 1 of 2." On page two, it reads "page 0 of two." I just can't seem to get the "page n of n" to work with spawned pages. Any suggestions would help.
Thank you

For each page's field number page you need to go to that page in the calculation script. You could also turn off calculations during the spawning of the pages and then turn it back on and recalculate the form.
// code to spawn template;
// turn off automatic calculation;
this.calculate = false;
var t = this.templates;
var T = t[0];
T.spawn(this.numPages, true);
// trun automatic calculation back on;
this.calculate = true;
// force recalculation;
this.calculateNow();
// end spawn template;
// custom calculation script for numbering pages;
var cField = event.target.name;
var aField = cField.split(".");
if(aField.length > 1) {
// get page number for form field from field name & go to that page;
this.pageNum = aField[0].substr(1,1);
// update field's value;
event.value = (this.pageNum + 1) + " of " + this.numPages;
// update field's default value;
event.defaultValue = event.value;
// end custom calculation for numbering pages;
