How can you duplicate pages without having the fields read each other?

As you mentioned, setting up a template and executing a simple script is an option. When you first set up each of the initial pages as a template page, you'll give each a name, such as P1 and P2. You can then execute the following JavaScript code in the interactive JavaScript console (Ctrl+J) to create 13 additional copies of P1 and P2. The fields will be renamed so they are independent.

// JavaScript to create duplicate pages from templates P1 and P2

var num_copies = 13;  // Set the number of copies here

var T1 = getTemplate("P1");  // Use the actual tempate name here

var T2 = getTemplate("P2");  // Use the actual tempate name here

if (num_copies > 0) {

    var oXObjT1 = T1.spawn({nPage: numPages, bRename: true, bOverlay: false});

    var oXObjT2 = T2.spawn({nPage: numPages, bRename: true, bOverlay: false});

    if (num_copies > 1) {

        for (var i = 1; i < num_copies; i += 1) {

            T1.spawn({nPage: numPages, bRename: true, bOverlay: false, oXObject: oXObjT1});

            T2.spawn({nPage: numPages, bRename: true, bOverlay: false, oXObject: oXObjT2});

        }

    }

}

To execute the code, select it all and press Ctrl+Enter, or Enter on the numeric keypad

You need to have the same fields on each page BUT each one must have an unique name, otherwise they share their content.

When you right-click on a field in Acrobat Pro, you can:

"Duplicate across pages" : does what it says, without renaming fields.

"Create multiple copies" : does what it says and rename fields, but only on one page.

So:

- Create a big sized blank new PDF, let's say an A0 format (you can use this free tool).

- Cut and paste all your fields into this new PDF.

- Select all fields : Right-clic : Create 14 multiple copies (this is why you need a big sized PDF).

- Cut and paste each of the 14 group of renamed fields into your 14 pages.

You can do it very easily using this tool I've developed: Custom-made Adobe Scripts: Acrobat -- Duplicate Page (including Form Fields)

In "Prepare Form" mode, Select all the fields you want duplicated and right click to show the popup menu. Towards the bottom there is an option for duplicating across pages.
