Have a form field (text box) mirror the text/data entered in another form field. (i.e. user enters column names for table on first page, then column names are displayed later in document)

So in a very low-level kind of way, I am trying to mimic an excel file. I want the first page of the pdf document to act as the "master data" sheet and the preceding pages will grab text and numbers from that page. I have never worked with javascripts before so the syntax is very confusing. I understand that you can create a calcuation under the "Calcuate" tab (under properties of a form field), but it only deals with numbers. Any help would be great!
