Javascript (Adobe Acrobat XI) populate 2nd page form from inputted answers from 1st page in form

I want to start by saying I'm NOT fluent in javascript, however, I am learning and can read the code and comprehend it. I make professional fillable PDF forms, using javascript to perform actions and calculations, but I've never had to do this before. My request is specifically for Adobe Acrobat XI Pro javascript.

I have an order form I created. I've added a button (called 'Create Invoice')on the page to adds a page (using:var a = this.getTemplate("Invoice"); a.spawn();) after the order form that presents the information that was entered or calculated from the first page. I ONLY want to show fields on the invoice that were selected on the first page.

Here's a screen shot [link] of a portion of the Order Form (pg 1): [IMG]http://ift.tt/1zjZ47Y] (I can't post images until 10 reputation)

So on the Invoice (pg 2) I want ONLY the (2) items chosen above to show, in immediate succession: [IMG]http://ift.tt/1JSJGuk] (I can't post images until 10 reputation)

The DESCRIPTION column will ideally concatenate the "Saddle Name" + "Color". The rest of the columns should be obvious (fill in with the associated fields for each item ordered).

So, what should the code look like for this? And should the Javascript be put onto a field or Document Javascripts?
