How do I set up a field on pg 1 of my form for the user to enter a name and then information autofills in a "name" field on all susequent pages? User cannot access the name field on any page except page 1 when they enter it.

I tried that and it doesn't so what I want it to do.  That still allows the form user to change the information on page 2 or 3 or 4 and it will change it throughout the document.  I want them to enter it on page 1 and the info carries to the subsequent pages and cannot be changed or entered in any other place but that first field on page 1.  If I lock the fields on subsequent pages, it locks the first page too.  I've tried overlaying the fields with hide and show field features.  I just cannot get it to fill page one and then act like a header for the remaining pages with no access to enter anything on the subsequent pages.
