Dynamic Section Headings with Spawned pages

Question

Hi, I have a built a PDF document in acrobat, where i have spawned pages included. I have achieved dynamic section headings (3.1, 3.2, 3.3 etc.) for the document using the following script for a first in line of spawn pages event.value = "3." + ((event.target.page - 5) * 2);

this.calculateNow(); The problem that i am having is that using this style of code then also modifies section headings after where the spawn page is placed. I have 4 different spawn pages that slot in as additional test pages if needed. I need some help to be able to set a field to start from 1 and then subsequent add fields to find that field and add .1 to it, this needs to work across the spawned pages too. I have attached a redacted version of the document, if you navigate to page 8 and use the button the add calibrations it works nicely, but then it changes the validation section headings and subsequent add on pages for validations too. Any help would be appreciated, i have been trying to wrap my head around how to make it work. I thought about using this.numpages() but the total amount of the pages is always changing too. P.S. Damn my boss for throwing this spanner into the works of an almost completed document!

I think i just figured out why it wont work. Because there even though the original template is hidded, it still sees the button to add.field on it so there would be 2 of them which makes the calculation fail. I cant set the rename for the page to true as i have alot of linked calculations in there. Any guidance would be appreciated.

Ok... so now just talking to myself, but i thought i might post that i figured it out as it could help others.

What i did in the end, is created the following script to add the check box that spawns the pages (specific module of the document) to add the field to the last of the spawned pages which would be page 8 (there are 4)

var f = this.addField("VVA LINK", "text", 8, [10,30,80,10]);
f.display = display.hidden;

VVA LINK being the field name to reference for the extra spawn pages that can be made from the last page of the spawned module.

I used the following script to calculate the section numbers. Originally my JS console was going nuts with errors due to null values even if the extra pages were not spawned as they were trying to calculate in the background. I put the calculation into an if statement

if (this.numPages >= 13)
{
var VH = this.getField("VVA LINK").page;
var VVA = event.target.page;

event.value = "4." + (((VVA - VH) * 2) + 1);
this.calculateNow();
}
else
{}

This script references the page for the VVA LINK field that is hidden on the page before it, then uses the page numbers to calculate the difference between them to give you your section number (4.2, 4.3 etc.). It only calculates if the pages are equal to or greater than 13 pages, in my case, the document comes to 12 pages when the module is spawned. so i only want it to calculate if this extra page is added, making it 13+ pages.

Hope this can help out someone too.

I'm not sure what the issue is, exactly... I added a page and the headings on it are "3.5 Calibration Test" and "3.6 Calibration Test", which seems correct to me. Please clarify what you expect to happen instead.
